The primary rule (currently) is civility to other members, i.e. avoidance of vulgarities or direct insults. Frequency of posting is not an issue. Fortunately for me, being long-winded in a post is legal. Yes, I admit to getting on a "soapbox" now and then. Though brevity is the soul of wit, even the US Congress allows long-winded speeches as a delaying tactic. For our UK friends, this tactic is the meaning of the word "filibuster" - which we might mention and some non-USA members might not understand.
Strictly speaking, for this forum, the specific topic isn't an issue. The REAL problem is whether it is inflammatory. Even the USA, which has a "Freedom of Speech" clause in the first amendment to the U.S. constitution, has laws against certain types of hate speech and speech that might incite to panic or riot. The forum doesn't have a "moderator of moderators" yet - but we DO have moderators in general.
