You cannot delete your account, at least when I browsed the forum information. You can join, but you cannot unjoin. When I browsed the membership list, it showed a membership with 200 times the people that actually participate. Some are probably dead, but you can't delete your account. So if you are being chased by hit men from the CIA, or you need to become unreachable for your own safety, you are out of luck. When the religious majority or the government comes to kill you, they will check the forum membership first and trace it back to you.
We apologize for the inconvenience.
