True, this keeps the community small and those work really well without moderation.

The moment it becomes a bit more popular, shit hits the fan. I am still for a light approach. Banning spammers, trolls, and illegal porn posters is a separate issue for me, but many platforms began to delete unpopular opinions.

The most heavy handed moderated places are very often the most toxic ones, I think they are far worse than free for all examples. Given, that might not work for the masses.
