If there's a sufficiently large number of people whom you want to exclude, the problem might be that you're simply in the wrong group. It clearly keeps attracting folks you don't want to be in a group with.

And if your group has a very large number of subgroups, it's a sign group health is deteriorating. Side channels are healthy, but if they become the main mode of conversation, congrats, you're starting to develop cliques.
