There is much that goes into being a dirty player. It isn't merely doing illegal things on the court, though that is a huge part of it. A key element to being a dirty player is getting away with whatever dirty deed one performs. Another pivotal part of it is the ability to get under another players skin. It doesn't necessarily have to be a flagrant foul or a punch to the nose, but maybe bumping repeatedly when they walk down the court, or throwing little elbows when no one is looking. The players on this list are all masters of the art of being a dirty player. Admittedly, there aren't any players that currently play in the NBA on this list. I think that with replay technology and the strictness of the rules it is impossible for a player to be as dirty as in the 80's and 90's.
