I would support this idea for two reasons. 1: Players will find their own way of doing this anyway, so it is impossible for SE to stop it (jerks or otherwise) 2: Each and every player has the RIGHT to decide who they want to play with, jerk or not. If they only wish to play with people who have cleared already they have the right to do that. It isn't about nice or mean, its about freedom to choose, which we all have.
