A question for those talking about how the law is the only system that should be deciding this stuff.

Suppose I run a community online. Suppose several women come to me and say they've been sexually harassed by a senior male member of the community. Suppose that male denies it. What do you expect me to do? Call the cops? That doesn't seem very feasible. Just ignore it? Suppose the accusations are true; without the law saying they're true, I'm supposed to just let someone who might be sexually harassing other community members stick around?
