What sort of post or comment gets you downvoted the most? Especially if you don’t think it’s bad behavior in the first place, or don’t care. Does not have to be on Lemmy, but we are here…
One of the good things about Lemmy IMO is that it’s small enough to see the posts that are unpopular. If you do “Top Day” on most channels, you cash reach the bottom, see what people here don’t like.
As far as comments, attempting to rebut the person who is telling me my post sucks, is what gets me into negative numbers most often. The OP is going to voite it down, of course, and nobody else cares, usually.
If you call both sides right/wrong when both sides are right/wrong, both sides downvote you.
Mention a third option, middle ground, or reasonable compromise is a downvoting.
Tell them to chill, you might have well stuck a hornets nest up you ass. There’s a reason you occasionally see people just admitting they were wrong or changing their mind get sent to the front page, its just rare.
