Is it a PTB move (!yepowertrippinbastards@lemmy.dbzer0.com) to ban a user if their only activity in a community is downvoting posts?
The behaviour baffles me a bit. If they dislike the majority of the posts in a community, why are they subscribed? Or if they are browsing by /all, why have they not blocked the community? Are they under the mistaken impression that Lemmy has an algorithm which uses downvotes as an indicator for “show me less of this”?
Has anyone else encountered a “serial downvoter” in any of their communities?
You need to know why.
I went through days on Reddit where I would not find something posted that I wanted to upvote and found posts that, while maybe good for another community, were not fitting my definition of the intended topic. As a non-mod, you can’t directly shape the content, but you can vote.
Like you said, they also might not understand that downvoting things from a particular community will not make it show up less.
Just ask them. If they’re a jerk, you can still ban them. If they are ignorant but cool, you can help them be a better netizen.
