Yep, in fact the SA Forums entire business model was "arbitrary and capriciously" banning people so they would re-register and pay the 10bux. They had rules, but they were fungible enough so that intelligent and hilarious people wanted to see what they could get away with. Racism was strictly against the rules, but some people could post the N-word "because they are funny" (and friends with the admins).

Around 2007 or so, SA stopped being an "internet comedy forum" and started being "serious internet business" and that's when I lost interest.
