Yeah, I'm starting to consider using a sort of password/phrase on future RP's. I'm getting kind of fed up with people not following certain rules.

People get smart about that. They scan through the rules to find the passy into the game without reading the rules. You can make the password more complicated to figure out, but that generally becomes a pain to everyone that plays fair.

Harsh bio screenings have helped keep especially bad players or character away for one RP I'm in, and a policy of rejecting players that aren't ever active and leave without warning, if they come around again. It often tests how well the player takes criticism, how willing they are to change or fix something, how good of a sport they are, etc.
It also scares away good players or rejects decent to good players, either by not accepting what they did, or by killing their enthusiasm after the bio screening experience.
