Replying to Has NS ever been sued?

I read some pretty inflammatory shit in some threads on here, and it got me wondering: has Newschoolers ever been sued? I mean for anything-- libel, copyright issues, content, or anything else. How hard would it be to sue a website? When you sign up as a member, do the terms of service bar litigation? Admins, maybe you can weigh in.

DISCLAIMER- I have no intention of suing NS, I'm just wondering about NS's legal background for curiosity's sake.
