Well as I mentioned somewhere before, I’m still new here, but it’s seems fairly normal to me so far. On Reddit I’ve been temporarily or permanently banned from Subreddits like for the silliest things, when a mod doesn’t like you, there is no point. They will call you names and whatnot, doesn’t matter, appeal process? Doesn’t seem to exist.
Now how this works on Lemmy is still an unknown to me, though I do think Lemmy is too “complex” for the average internet user and so won’t be able to gain a similar “succes” in terms of userbase and ease of use.
