> I'd give the mod team the benefit of the doubt that the offense they've all resigned over is not so mild that it could be committed unintentionally.

I don't think that's necessarily a safe assumption, particularly in today's cultural and political environment.

The people who freak out over trivialities usually don't resign; they try to get others fired.

Sometimes they resign when they find out that they can't get others fired.

I don't know whether that fits in this case. I'm inclined to think not; I suspect that those who freak out over trivialities, try to get others fired, find out that they can't, and then resign, tend to have a public hissy fit when they resign. I'm not sure that what the Rust Moderation Team did counts; they seem to be trying to not air dirty laundry (or what they perceive to be dirty).
