So, I’m kinda new to this Lemmy thingy and the fediverse. I like the fediverse from a technological standpoint. However, I think that, if we gain more and more traction, Lemmy (and by extend the entire fediverse) is a GDPR clusterfuck waiting to happen. With big and expensive repercussions…

Why? Well, according to GDPR, all personal data from EU users must remain in the EU. And personal data goes really far. Even an IP-address is personal data. An e-mail address is personal data. I don’t think there is jurisprudence regarding usernames, so that might be up for discussion.

Since the entire goal of the fediverse is “transporting” all data to all servers inside the ActivityPub/fediverse world, the data of a EU member will be transported all over the place. Resulting in a giant GDPR breach. And I have no idea who will be held responsible… The people hosting an instance? The developers of Lemmy? The developers of ActivityPub?

Large corporations are getting hefty fines for GDPR breaches. And since Lemmy is growing, Lemmy might be “in the spotlights” in the upcoming years.

I don’t like GDPR, and I’m all for the technological setup of the fediverse. However, I definitely can see a “competitor” (that is currently very large but loosing ground quickly) having a clear eye out to eliminate the competition…

What do y’all thing about this?

I'm not an expert in GDPR and will leave the technical side to those who are, but the fact that the EU actively present at the Fediverse with among others the @EU_Commission represented at their official Mastodon instance, I would be surprised if the GDPR was suddenly weaponised against it.

GDPR was written with the intention of empowering users over corporations. The Fediverse has the same goal.

[–] infamousbelgian@lemmy.ml 1 points 1 year ago

Wholesomely and fully agree... Just hope that Lemmy doesn't get sued over it...

[–] klingelstreich@feddit.de 1 points 1 year ago* (last edited 1 year ago)

IANAL, but he GDPR is quite reasonable and if Lemmy did the right thing (c) it would not be a problem I think. Transferring data to a jurisdiction, like for example the US, where people do not enjoy the same level of data protection comes with risks for any eu citizen. Therefore, it is important that any new user of Lemmy/ActivityPub is educated on what's actually going on here and the consequences of posting on Lemmy for their personal data. Article 49, 1a) of the GDPR provides an exemption for the rule this posting is about if

the data subject has explicitly consented to the proposed transfer, after having been informed of the possible risks of such transfers for the data subject due to the absence of an adequacy decision and appropriate safeguards

Why can't we have that? Add a step to the signup process that explains the basics of how a decentralised community works: even if you sign up to a German Lemmy instance, Lemmy is a global community, your data may be transferred to any place in the world and that means that you won't be able to enjoy the rights and protection you may expect on a German server. Click the "accept the risks" button to continue. Go to this link if you ever change your mind to stop federation of your content and attempt to remove it from any place it has already been federated to.

Even cooler if we can somehow record the jurisdiction of instances and build mechanics that act on that information, e.g. during federation.

And personal data goes really far. Even an IP-address is personal data. An e-mail address is personal data.

Thankfully, Lemmy instances do not transport this kind of information about their users to other instances!

[–] hardypart@feddit.de 0 points 1 year ago (1 children)

Maybe not IP addresses, but every post and comment you make is your personal data.

[–] sunaurus@lemm.ee 10 points 1 year ago (4 children)

Public posts and comments are, well, public (and there's no expectation from users that their posts and comments would be private, considering the nature of what Lemmy is).

The only way to not transport public posts and comments to the rest of the internet (including but not limited to other Lemmy instances) would be to completely disconnect an instance from the internet 😅

[–] LollerCorleone@kbin.social 5 points 1 year ago (2 children)

This. Federation doesn't transfer private data of the user, just their public facing profile and posts. There is no expectation of them being private.

[–] ShellMonkey@lemmy.socdojo.com 1 points 1 year ago* (last edited 1 year ago)

The admin of a site, not only fedi ones but any site, can only control what's in their reach. A user could ask as per the GDPR to have their profile and history removed, but data not in the control of the admin is not their responsibility.

Consider it from the perspective of a traditional site, if someone takes a screenshot of something you post and puts it up somewhere else the originating site has no means to control that or to remove the data from a third party location. The same issue has been fought since the dawn of the internet, people trying to erase past events that have spread far and wide. There are even proffesional services available to try and scrub such things, but in the end if all they can do is send takedown requests to another jurisdiction it's going to be an impossible task.

[–] hardypart@feddit.de 0 points 1 year ago

ITT: People that don't undertand the difference between "personal" and "private". My posts and comments are my personal data, even if they're public, and I have the right to decide what happens with it and if it should stay public. That’s what the GDPR says and that’s exactly what OP is referring to.

[–] hardypart@feddit.de 2 points 1 year ago (23 children)

You're confusing "private" with "personal". My data can be public, but it's still MY data and I have the right to decide what happens with it and if it should stay public. That's what the GDPR says and that's exactly what OP is referring to.

[–] sunaurus@lemm.ee 5 points 1 year ago

You are able to edit and remove your posts on your Lemmy instance. Other Lemmy instances may or may not also reflect these changes, but your instance admin does not have any authority or responsibility to ensure that your previously public posts get deleted anywhere else in the world other than the instance they run.

That's exactly how it works everywhere, it's not a Lemmy specific thing. For example, if you write a public blog post on some public blog service, and later delete it, then it won't be the responsibility of the blog service owner to remove your post from elsewhere on the internet. It will be your own responsibility to manually request removal from other services which have copies of your post (like archvie.org etc).

Posts and comments are not inherently personal data (although they might, of course, contain personal data).

A post of any sane length, though, likely is covered by copyright. Them being public is entirely irrelevant to that in terms of what others are entitled to do with them.

On the other hand, as you say, none of (gestures wildly) this works very well if people start leaning too heavily on that.

Neil Brown did quite a good write-up on the legal standing of the Fediverse late last year: https://decoded.legal/blog/2022/11/notes-on-operating-fediverse-services-mastodon-pleroma-etc-from-an-english-law-point-of-view

There's a section part way down about GDPR, but the answer is "it depends"

[–] infamousbelgian@lemmy.ml 3 points 1 year ago

Thanks! The info actually makes sense. Also, do note that every EU country has their own specific implementation of the GDPR law with very small differences. So this is written according to the UK implementation, but the BE implementation might be just a bit different.

All complicated stuff...

[–] wintermute@feddit.de 1 points 1 year ago (2 children)

Since the entire goal of the fediverse is “transporting” all data to all servers inside the ActivityPub/fediverse world, the data of a EU member will be transported all over the place.

It doesn't work like that, think of your instance being a proxy to the fediverse

[–] infamousbelgian@lemmy.ml 5 points 1 year ago (1 children)

Is it? I read somewhere that data effectively gets "copied" to the different instances? But that might be wrong info :p

[–] hardypart@feddit.de 2 points 1 year ago (1 children)

You're right. If someone from feddit.de subscribes to a lemmy.world community, the entire content of that community is going to be copied to the feddit.de server and that's the exact issue OP is referring to.

[–] mkulima@baraza.africa 0 points 1 year ago (1 children)

Then it should be the responsibility of the EU people to avoid joining the fediverse. I do not see a practical way to align with GDPR. The effort is non-trivial and the rewards are extremely minimal.

From your perspective, what should be the way out?

[–] hardypart@feddit.de 1 points 1 year ago

Then it should be the responsibility of the EU people to avoid joining the fediverse.

The instances are providing their services in the EU, so it's legally up to them to comply with the GDPR.

From your perspective, what should be the way out?

Honestly, no idea. I'm not even sure if Lemmy in its current shape violates the GDPR in the first place, but if I were the admin of a large feddit instance in the EU I would make sure to get advise from a GDPR consultant.

[–] hardypart@feddit.de 0 points 1 year ago (2 children)

But when a lemmy.world user subscribes to a feddit.de community, the entire community will be copied to the lemmy.world server, or am I wrong?

[–] curiosityLynx@kbin.social 2 points 1 year ago (1 children)

You are indeed wrong. The email and IP addresses and passwords for example don't get copied. I'm not well versed enough about how it works to go into more detail.

[–] hardypart@feddit.de 3 points 1 year ago (1 children)

You are indeed wrong. The email and IP addresses and passwords for example don’t get copied.

I never said that IP addresses and passwords are getting copied.

The thing that no one seems to understand here is that all my posts, comments and votes and everything are my personal data. My data can be public, but it’s still MY data and I have the right to decide what happens with it and if it should stay public. That’s what the GDPR says and that’s exactly what OP is referring to.

[–] SkyNTP@lemmy.ml 1 points 1 year ago (1 children)

If what you say is true, then... Email is illegal in the EU. EMAIL.

Yeah, no, GDPR, although well intentioned against large corporate entities that have all the power in centralized system, is a relic in the context of federated technology. It is both completely unenforceable, and also not really relevant.

[–] hardypart@feddit.de 2 points 1 year ago (1 children)

If what you say is true, then… Email is illegal in the EU. EMAIL.

No, but there are actually certain things you need to take into consideration when it comes to GDPR and email.

What the GDPR says:

Data erasure is a large part of the GDPR. It is one of the six data protection principles: Article 5(e) states that personal data can be stored for “no longer than is necessary for the purposes for which the personal data are processed.” Data erasure is also one of the personal rights protected by the GDPR in Article 17, the famous “right to be forgotten.” “The data subject shall have the right to obtain from the controller the erasure of personal data concerning him or her without undue delay.” There are some exceptions to this latter requirement, such as the public interest. But generally speaking, you have an obligation to erase personal data you no longer need.

What it means for email: Many of us never delete emails. There are plenty of good reasons: We may need to refer to them someday as a record of our activities or even for possible litigation. But the more data you keep, the greater your liability if there’s a data breach. Moreover, the erasure of unneeded personal data is now required under European law. Because of the GDPR, you should periodically review your organization’s email retention policy with the goal of reducing the amount of data your employees store in their mailboxes. The regulation requires you to be able to show that you have a policy in place that balances your legitimate business interests against your data protection obligations under the GDPR.

I still don't see a reason why Lemmy shouldn't be affected by the GDPR and why it's probably not compliant in its current state.

[–] SkyNTP@lemmy.ml 1 points 1 year ago (1 children)

The last paragraph you quoted is in reference to individual responsability and how they access the data. It's equivalent to saying "don't look at at this Fediverse post: you are GDPR compliant!". This only helps you in litigation. We both know that says nothing of where the data can exist. And this is true for any federated system, including email.

It's also completely asinine. Suddenly we need to burn snail mail after reading it? Why receive any mail at all if everything is a giant piece of liability? There's a social contract in communication: a certain assumption that if you give someone a piece of informtion, you are doing just that: giving, not lending. "Lending information" upsets the social structure. GDPR has to be tempered in reality, and this starts even before the fediverse.

Like I said, GDPR is imperfect. It was written in the context of and solves a problem created by centralized institutions and large beaurocracies. It is also completely unenforceable in a decentralized system. It hardly seems relevant anyway.

Realisticalpy speaking, those tempered interpretations are probably already existant, and there is already enough precedent for this to be a nothing burger.

[–] hardypart@feddit.de 1 points 1 year ago (1 children)

This whole thread is full of interpretations and gut feelings. Literally no one here backs up his claims with any kind of evidence.

[–] SkyNTP@lemmy.ml 0 points 1 year ago

Unsurprising considering we are in uncharted territory here.

[–] wintermute@feddit.de 1 points 1 year ago (2 children)

sure, but no personal data like email/ IP

[–] hardypart@feddit.de 2 points 1 year ago* (last edited 1 year ago) (1 children)

I think you, being an admin of a huge Lemmy instance, would be well advised to educate yourself on the difference between "public" and "personal" when it comes to GDPR compliance. All the data I create here is my personal data, no matter if it's my IP, my mail address, posts, comments or votes and the GDPR says that it's my right to decide what happens with my data and if it should stay public. The fact that I post something publicly doesn't make my data non-personal.

[–] wintermute@feddit.de 1 points 1 year ago (1 children)

I'm quite well advised, maybe I`m using wrong terms as EN is not my native language.

[–] hardypart@feddit.de 1 points 1 year ago* (last edited 1 year ago)

OP said

Since the entire goal of the fediverse is “transporting” all data to all servers inside the ActivityPub/fediverse world, the data of a EU member will be transported all over the place.

and says that's a GDPR nightmare (and he's right according to my understanding of the GDPR).

You said:

sure, but no personal data like email/ IP

Which implies that email addresses and IPs were the only personal data that's relevant in terms of the GDPR, which is simply not true.

I think decentralized services like the Fediverse are a new challenge for the GDPR and that OP is absolutely right in expecting this to blow up one day.

Again, please stay educated and up to date about this whole topic. We don't want you to get into trouble for providing something beautiful.

The content of comments and post can also contain personal data.

[–] ledditor@leddit.minnal.icu 1 points 1 year ago

"Exchange with non-compliant platforms can be restricted based on a case-by-case analysis. ": I quote this from an article from European data protection supervisor website https://edps.europa.eu/data-protection/our-work/publications/techdispatch/2022-07-26-techdispatch-12022-federated-social-media-platforms_en. I think the platform will evolve to solve the existing issues such as The right to be forgotten.

[–] Fermiverse@kbin.social 1 points 1 year ago

Kbin.social and feddit.de are hosted in Germany. That's why I signed up there.
