Just avoid name calling or making enemies. The less you get reported, the fewer warnings you get (yes, to a degree, it's a popularity contest, but the current moderating staff seems pretty fair to me).
Since narrowly avoiding a banning, I've received no infractions of any kind from the moderators (although, admittedly, I've deserved many). It's been a couple years or so.
Threads on homosexuality, politics or religion are definite no-nos. I try to avoid the general board altogether.
You can talk all you like about not agreeing with homosexuality for whatever reason (as far as I can tell), but calling someone a dirty *** should earn you a slap on the wrist (if you get reported...which is likely if you're an ***...).
