I hadn't used it, but I looked at it in the past. They didn't control the block lists, it was entirely up to you. Basically it had "lockout filters" which would mute people you didn't follow/hadn't interacted with/new profiles/not in your follower network/etc, you can still see those messages and those people can still see you, they just don't trigger notifications. It also had the ability to block people based on a Tweet's interactions - so if someone writes a Tweet attacking you or your identity you can not only block the author, but everyone that liked or retweeted it (and by associated supports those view points). On another note, I don't think it's necessarily wrong to be in an echo chamber with peers, if the alternative is exposure to constant arguments, disagreements, trolls and toxicity causing damage to your mental health, so long as you're aware. One persons echo chamber is another's supportive environment.
