You're on Lemmy.world, where my impression is that the threshold is pretty high before they defederate. If you want to be kind and see as little garbage as possible, you could for example join Beehaw, which has a focus on kindness. LGBTQ+ people who are particularly tired of bigots can join Blahaj, where the mods are very trigger happy about weeding out that kind of behaviour.

If you're unhappy about every approach to moderation out there, you can start your own instance and do it yourself. Of course most people won't, but it nevertheless renders them in less of a position to complain.

And yes, moderation cannot ever be perfect. It takes a lot for users to leave a community due to disagreeable moderation. But still, users here have a lot more choice.

Personally I'm testing a platform where problematic users (such as the one starting this comment thread) are marked with warning signs, so that I can identify likely trolls right away and alter my interaction with them. It's pretty neat.
