Like most other people here, I originally came here from reddit. Ive been having a blast so far, and I much prefer the forum-style of this. After about a week of using Lemmy I realized there was something intrinsic to reddit that Lemmy doesnt have. And I wont miss it. Too many people on reddit were way too horny. I was really annoying, but Lemmy seems way more chill. Plus its refreshing knowing that the people on here arent all bots.
Sorting by all/hot, you can come across some nsfw communities, although some of them seem really shady.
