If you want a board which works, you have to moderate it. If you don't have time, well, haters and trolls are going to take over. When you don't/can't enforce your own rules, haters and trolls do take over.

I've posted any number of serious political topics under more than one name. They get NO response or they get trolled and threadjacked. By people whom YOU refuse to even personally criticize.

So stay or go, but don't pretend to be above it all. Doing nothing is also an action.
