You know you have an RP problem when people start to create there own plot and use it as a way to advance the story without actually telling the GM. 

You know you have an RP problem when a player runs off somewhere and then nothing happens as they grow bored hoping someone would chase them.

You know you have an RP problem when the cops can be played by players, my very first RP fell apart because of that and the fact the GM was hardly around.

You know you have an RP problem when one writes I swing at you and kill you instantly without saying how they did it or what they were thinking when they did it. Also the fact they don't give the other a chance to defend themselves, I am on about NPC's being killed and such though it happens with players as well. It is just I am god..... You die now.
