Obligatory ‘your mileage may vary,’ but lemmy seems to be no better in any regards than reddit or similar. The top 20 posts in any community are from power users and/or mods of such community. They enforce rules on a biased, per-basis quota rather than rules as written.
Full discourse: just got a 3-day ban from news@lemmy.world because I was being ‘uncivil,’ despite being the first attacked. Another user mentioned the lack of punctuation from the OP, and I followed through with a ‘failed grammar’ joke.
Rule one of /c/news@lemmy.world is ‘be civil; if you see bait, report and move along’ (paraphrased). I wasn’t even baiting and these people threw their expired chum at me.
Literally everything after that was criticism, judgement, and personal interpretations. Everything from ‘don’t judge the illiterate,’ to, ‘why would anyone bother with your bs?’ (see how speshul that one is?) When I shot back, the smooth brains doubled down.
Ultimately lemmy as a whole is becoming more like reddit every day, and I’m just rocking on the fence deciding if it’s worth keeping.
I don’t even like .ml but at least they’re consistent.

I agree that it’s a slippery slope, but it’s not yet Reddit.
There are no alternatives. For the IT crowd, Hacker News has an automatic shadowban for VPN users, and Lobsters is invite only. Lemmy/Piefed is still good IMHO.
