Definitely read the community guidelines. Like most places that have moderators there are limits to what you can say and generally on most boards if you question a decision by the moderators the guidelines for most moderated boards do say to do it in private message or other non-public communication rather than confronting the moderators repeatedly in public.That other people seem to be breaking the rules is no reason to assume that you can get away with it, and some people are very good at staying just barely the legal side of the rules. If you aren't acutely aware of the rule and where the line actually is you can easily cross it when someone else did not.
