From the linked description:

More accurately, the Lemmy community is surprisingly tolerant of a wide range of opinions

No, no they aren’t. Communities have general set of opinions and they will often downvote you having the wrong one even if its as trivial as preferring the “wrong” team in a sporting event.

Q: Why doesn’t the bot notify for bans?

There are a few users who get banned or unbanned very day, as the pattern of user comments and votes changes over time. It’s important that bans be “lightweight,” and always reversible for anyone who is banned.

If I was randomly unbanned without being actually transgressive and I never knew when I could post I would very very shortly stop engaging with a community.

Q: Won’t people learn to fake upvotes for themselves and trick the bot?

It’s worse most comments most places will have near zero engagement. Threads are full of stuff only a few people upvoted it would be easy to use this system to harass and silence people. Hell People look at karma as the communities judgement and are actually more likely to downvote less likely to upvote if an innocuous comment is shortly reduced to -1

Is there a lemmy instance that isn’t basically trash?
