Been on the lemmygrad for four years. Was banned simply for my alternative opinion that a guy who was rejected by a girl should exclude her from his life if he retains feelings for her. Didn’t break any rules, but the idiot in the moderators didn’t stop it. I used to think lemmygrad was a cool place for leftists. But it turns out it’s an echo chamber for online morons. I regret that I ever defended this place.
I think a lot depends on the moderators. There are normal ones who give freedom of speech and opinion. Punishing only for breaking the rules or real thrash posting. In such cases it is hard to call the community an echo chamber. And there are some assholes, like on lemmygrad, who will ban you forever for the slightest deviation of your opinion from their own. In such a case, the community is doomed to degradation. As we can clearly see from my ban without any explanation, respect and fair punishment for the real rulebreakers.
