> That's is due to active moderation,

Just, FTR, there's always been the problem of how much moderation is required to keep the discourse (in a group) flowing without being so restrictive as to only be about the moderators.

See IRC, which (IMO) can be over-moderated, channel ops used to be very much about themselves, vs Usenet, which had no moderation at all (and was "destroyed" by google groups making access trivial for troublemakers), through to current things like Reddit which have some moderators.

It's (IMO) exactly like governance IRL - some countries overdo it, and some underdo it.
