Posi-Hitler
Purchasing an online forum with the belief of changing the forum for the better, only to ban everyone who does not agree with the new leadership and rules. Then running the board into the ground until no one posts anymore.
Those guys really pulled a Posi-Hitler on the weightlifting forums. They thought that changing the rules would make it a better place, but all they did was ban the people that made it entertaining. I see maybe 10-15 new posts a day when it used to be 100 or more.
