The more interesting question is what will happen when a known member of {insert bad group here} particpates and does nothing but make meaningful technical contributions. At some point, he'll be outed and then what? I think that there's a better than 30% chance that said person will be booted. My question is more interesting because the situation that I describe is far more likely. (It's almost a certainty.)
