Some high class forums, like RimfireCentral.Com, have moderators that police the discourse and eliminate the useless or disrespectful comments and occasionally their posters when repeated warnings don't resonate. Based on some of the stupid stuff I've read here over the years, the campfire could use more moderators.
I had 100,000 posts on rec.guns on the old usenet, before www gun forums.
I have seen a lot of forums come and go.
Mostly go, from overzealous moderation.
90% of the time they are being a good bouncer, and kicking out the riff raff.
But 10% of the time they are booting out anyone smarter than the moderator... and those are the best original content creators.
24HCF continues to grow as it is easier to skim past obnoxious jacka$$ posters that think they are funny, than it is to put up with a boring stagnant forum caused some low IQ moderator playing king of the mountain.
And I am paying money to belong to rimfire central.
