Here you go. Taken straight from the rules for ya:
Subjects to avoid. Anything that is discussing religion, politics, racist subjects or similar will not be tolerated on the site. Please also avoid spam threads, such as word games, post your pictures here or ‘which of these games to buy/sell’ threads. They have all been done before. All of them. Yes, even your idea. Also, we don't allow advertising on the forum, this includes referral links.
