EDIT: @mindbleach@sh.itjust.works shared something that might help to circumvent this shit:
Contained in these parentheses is a zero-width joiner: ()
Basically, add those to whatever you feel that might be filtered out, then remove the parentheses. The content inside the parentheses is invisible, but it screws with regex rules.
Yes, it is a shadowban. It fits perfectly what you said: the posts and comments are filtered and hidden from the others.
Here is another proof that this is a shadowban:
Left: the content is shown to the user when they're logged in, and they can still submit new content.
Right: the content is not shown to someone who is logged off.
On the other hand, a typical suspension leaves the content visible for everyone else, it tells the user "you've been permanently suspended from Reddit [insert gaslighting message]", and the user cannot submit new content.
Note that a shadowban is considerably worse than a suspension. Not that I care, though - I'm sharing this here because it is relevant for people trying to convince others to migrate to the Fediverse.
Oh that's weird. I just got straight-up banned the other day for saying something bad about Nazis 😂
How do you dare? You're as intolerant as them if you don't let them invade your spaces! 🙄
Serious now. I got a ban similar to yours years ago. "Multiple, repeated violations of the policies" = I told a self-identified Nazi to shoot himself. (10/10, great laughs were had at the butthurt Nazi. Would do it again.)
Fuck Nazis, fuck the KKK, and I'm not selling my wife's gun at this point. Too much at stake.
