Exactly. Promoting Lemmy/Fediverse has very much to do with learning how to moderate an instance / community.
Repeated bad behaviors should have users banned at some point. And this is way different from censorship (which exclude topics, not bad behaviors). For example you can’t invite nice interesting (leftist) people on an instance where users are terrifying others with awful stalinist claims and insults. It won’t be better than Reddit to them. Blocking the awful people for yourself is even worse because you don’t see the shit anymore, but new people will be confronted to it anyway as soon as they arrive. And this can really disgust them from the fediverse.
Really the problem is you don’t want to acknowledge the difference between diverging political views and agressiveness/insults/fanaticism.
You never say anything when people of your “political opinion” insult others, or call for brigading. So you let the harrasment and sealioning go on and seem happy with that. Maybe do something about it before complaining that other people complain here ?
