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 browse the modlog often.
This is nothing new. The AI "art" comms (it's probably just one mod but I don't know) often have hissy fits about people who don't like AI, and if people downvote them, those people get banned. I have never interacted with any of them, either the banned or the banners, but seeing people banned from stable diffusion comms for downvoting happens all the time, like several times a week, at minimum.
@robot_dog_with_gun@hexbear.net is right. It's some pissy generative AI slop lover loser who doesn't like people downvoting them and there is nothing wrong with saying so. That said, downvotes as a function suck, it's better when instances disable them. But if they are present on an instance, I don't think it's necessarily a bad rule that if accounts with no activity do nothing but downvote everything, they should catch a ban. Mostly because it sounds like bot activity. But whatever, it used to be mildly amusing to see the drama in the modlog due to the fragility of AI slop prompters, but it's so common that all novelty has long ago worn off.
As for seeing votes, mods can see who votes up or down on anything in the comm they mod. This might depend a bit on instance, but in general, I think that's the case. Admins can see who up or downvotes anything. And yes, there is a tool that in theory can show anyone who votes and how. Like this post for instance: https://lemvotes.org/post/lemmy.today/post/51863842 However, from my understanding, an instance can disable this from working, so that tool is basically opt-out. You won't see a hexbear name in the up or downvotes at lemvotes.org because hexbear has that disabled.
