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.
Those ideas get you banned, not downvoted.
Anywhere that bans ideas isn’t a place I want to be anyway. The woke crowd are fond of saying sunlight is the best disinfectant and just as fond of unironically sweeping dissent under the rug.
Not being silenced by actual fascists and being able to interrogate my beliefs was key in becoming better informed on a lot of subjects that don’t have any place in my actual life.
