Considering I just got “permanently suspended” for making a bad joke on WTF, no appeal possible (nobody replies), Lemmy seems more fair.
As getting banned for the entire site, so to speak, is really unlikely if not impractical versus Reddit where if one mod doesn’t like you, if left leaning (and they are all left wing fascists basically) you are F’ed.
Reddit is super left wing, Lemmy is too small (now) to compare or make any comparison to which is “worse”, so it can only be better right now.
I imagine it's probably used in the same sense as "grammar Nazi"... like no, they probably don't believe strictly in the tenets of National Socialism, but they're still acting like a Nazi.
