The game itself is really fun and griefers are much rarer than you might imagine from reading the forums. But yeah.... It's absolutely nuts there sometimes. The developer is a massive free speech advocate and doesn't mind hosting this horrible crap. But what's insane is that he gives moderator ability to some of the worst offenders. So I just don't know what's going on in his head sometimes.
There used to be a list of alternative servers, but seems to be gone now :-( Possibly nobody is hosting one any more. I'm tempted to do it myself, but I'm in Japan so the lag would be unacceptable anyway (I'd be playing by myself, which I do anyway...) But it's an option. If you can find a group of people to play with, it can be quite fun just to run on your own server. It takes very little CPU from my experience.
