UPDATE: The Unbans are showing up on modlog now.:

~~I have traded the month-long ban in the many communities for a 6-day ban in [email protected], which is a more reasonable ban~~. this ban has also been lifted now. I appreciate the cooperation from the mod over this misunderstanding.
So it seems i've gotten a month-long ban in..... over 30 communities across lemmy.dbzer0.com, sopuli.xyz, lemmy.ca, programming.dev, and several others, for this comment here.
Screen cap of comment for posterity:
It's directly replying to a comment saying they can't imagine why anyone thought otherwise about fish feeling pain, which is reasonable. You might notice the quotation marks, because it's satirizing people's mental gymnastics about fishes' pain perception. It was meant in jest, exclusively.
It seems likely that a single mod took this joke wrong and chose to ban me on every community they have control over.
I think it's as much of a fix as is possible. If your problem is the owner or admin of the server your best solution is to leave. On reddit that meant leaving reddit. On lemmy it means you have to find another instance
My understanding is it works slightly differently.
It means that all users of an instance which banned you won't be able to see your comments even if these are made on another instance. It therefore stops you from participating with all the users of the instance which banned you, even on other instances.
Thus my comment about the limited remedy.
