This makes me feel weird about the problem. It’s one thing when a very small minority takes control of an open projects. But when it’s simply a reflection of larger social dysfunction ... what then?

You can’t expect an open project to be healthier than the culture that fosters it.

You either restrict it, shut it down, or live with the dysfunction. Or, if you have the time and resource, create tons of red tape and the illusion of openness (i.e. Reddit).
