Saw this a lot on Reddit. Its not specific to here, just trying to gauge how people think. I’d see people posting about how “X said this! Have you seen what else they said in their site history?” And a stream of votebombing would happen.
I also wonder if this behaviour went the other way. Bias was confirmed, so profiles get a little boost? There are sites that hide posts and comments after a certain number of downvotes, but these always seemed to get the engagement even after.
Only if they seem suspicious to me as trying to push some kind of idea. Usually posts with leading questions such as “anyone else notice the anecdotal negative experience portrayed as norm”, comments where someone blames a demographic for something, posts that are on topic but have a blatant other purpose meant to start shit (such as cat pics in c/cats held by soldiers), etc.
In too many cases, the user is really adamant about whatever they have to say, and I just end up blocking them.
