Some admins really love watching who votes for what and banning people based on that.

You can disagree with that if you like but if it means they get pissed enough to defederate your whole instance, you lose.

If your instance is just you and a handful of others, no one will notice or care. But once you have 1000 users the amount of anonymous votes will be noticed and there will be consequences. Maybe not defederation but everyone banned for upvoting bigoted content will migrate to your instance and you'll be hosting the biggest shitbirds around.

I don't see a solution to this. As long as lemmy and mbin let admins snoop on people's votes that will be the dynamic and PieFed puts itself at a disadvantage by doing anything different.
