Not my account, but want to advocate for it. Because of, personally, I find it hilarious.
So, it seems like a mod with username MysticMushroom1776 @lemmy.dbzer0.com has some interesting policies about interacting with their content.
I agree that this user called PyroRondo has no content for 5 months straight. This is unusual but totally isn't against any rules of Lemmy.
As I suspect, they reacted to a few posts of MysticMushroom1776 @lemmy.dbzer0.com during random session of content scrolling. No brigading or any other types of harassment. I even suspect that these reactions were in communities connected to mod's AI art, not political ones.
And this for some reason triggered a ban in all comunities. Not in 1 or 2. Moreover, it seems like this mod uses specialized tools, that allow to track downvotes on their content made by other users with ability to get their usernames. I may be wrong, but I don't think that such tools are basic for moderators on Lemmy.
Edit: typo.
I bet 10 dollars, that mod hasn't even send a message to that person asking what that was a thing.
