FYI, bots and crawlers can simply ignore your robots.txt entirely. This is probably common knowledge around these parts, but I've run into clients at work who thought it was a law or something.

I do like the idea of intentionally polluting the data robots will see, as suggested by this comment. There's no reliable way to block them without also blocking humans, so making the crawled data as useless as possible is a good option.

Just be careful not to also confuse screen readers with that tactic, so that accessibility is maintained for humans. It should be easy enough if you keep your aria attributes filled out appropriately, I imagine.

Good luck.

I have a personal site.

It isn't great. Don't even have a domain name. My robots.txt is here

Why bother? I just don't agree with AI.

Block everyone but the crawlers you like. Blacklists are less reliable than whitelists

Maybe there's some IP address ranges to try block?

It's difficult because, for example, blocking the addresses OpenAI's crawlers use may inadvertently block addresses from Azure used by Bing or whatever.

I don't really understand the reasoning behind doing any of this, they didn't give a fuck about stealing clearly copyrighted content in the first place, why would they care about you (not OP specifically) begging them not to steal your stuff. (As long as theres no laws about this which afaik there aren't).

Easy. Add a section to your robots.txt file.

Pehaps the user (or in this case the bot) will not go directly to your website, but first to some method of captcha verification or something like that, or like those pages (SteamDB for example) that do not open directly but first open a blank page to verify your network and browser with a captcha.
