2C. Sometimes the behavior of the entire group can be changed by the addition of new members. Using a buddy system to get newcomers up to date is one way to break up a clique, for example.

2B. Make sure you've got some help from other group members if you're going to make public the bad behavior of certain members. This is a sure way to make enemies for yourself and the community project. If, though, you can structure a discussion that makes the subject wide open, it might work. For example, you might ask for a brainstorming session on how the community sees your project/group (What's our image?) as a way to address the rumor mill.
