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.
If the receiving instance cant view who votes, you open it up to extreme vote manipulation.
It’s trivial to start your own instance, and one could fork any code to counteract bans on their end or mass send votes without a set user behind them.
instance admins could reject votes from abusive instances and you could let mods see totals per instance
There’s other possibilities like using private set intersection and more to detect possible abusive patterns without sending raw data over between instances
