Full disclosure: I do still use Reddit, simply because of how much content there is on that site. But I'm tapering off to spend more time on Lemmy. I hope to see this platform grow.
If I had to boil down my description of Reddit into one thing, it would be "passive aggressive."
I've been banned from subs I've never even previously commented/posted to. But then I'll make a comment and it's been shadowbanned. It's so prevalent that I got in the habit of logging out to check that it actually appeared. I mostly stuck to commenting and made new posts rather infrequently, but it seems like some subs no matter what I posted it would get removed for very dubious reasons. One of the worst offenders was the sub for unpopular opinions, where they would just remove anything and say "must be an unpopular opinion."
