I’m a moderator on another site (nothing to do with trumpets) and we generally let silliness go, but name-calling and vulgar posts are deleted. Very much of that from the same person results in permanent removal. Same goes for people who want to do nothing but argue and are childish and arrogant.
I became involved in one of the recent disagreements here and was berated repeatedly even after trying to keep the discussion friendly. People who know it all and have a chip on their shoulder can be hard to deal with. Hey, I know that I don’t know it all, but I know what I know...
