You can in fact see the same mechanism I discussed at work right here in this very thread on HN. The original comment was flagged enough to be dead, hidden from the rest of the community to protect it from the fights it intended to start. It's not exactly the same as banning your account but it accomplishes about the same purpose at a more granular level. So HN is no less of the "echo chamber" you describe, yet you appear to find value in posting here anyway. Similarly, when BlueSky bans such users, little to nothing of value is lost.
