Image Problems.

[Phimuteach]

Keep in mind, this is based on the (little) information you've given us on the situation.
I would try to solve the problem first by having friends or bigs of the girls (who's willing) address the issues the chapter is having with their behavior. They could come up with goals or an action plan to improve. Then if these girls aren't making any positive progress they should be brought to the standards board.
