I guess you never have heard about Cyber bullying, Cyber Stalking, Slander, Libel 
Man, here is where doing IT for a buncha law firms is starting to come in handy

I am not a lawyer but........
Slander is oral defamation. Since you cant hear us, it doesn't apply. Oh please dear lord tell me you cant actually hear us.
Libel is the communication of a statement that makes a claim, expressly stated or implied to be factual, that may give an individual, business, product, group, government, or nation a negative image. You would have an exceedingly difficult time proving that when someone called you a meth head, that it would be implied to be factual and not just an insult based on the poster's opinion of the quality of work and idea the work is based on. That and you are never directly identified as the user of meth on the page.
Cyber-bullying "involves the use of information and communication technologies to support deliberate, repeated, and hostile behavior by an individual or group, that is intended to harm others." Hostile behavior by an individual, like I dunno repeatedly threatening people with physical harm when they disagree with you. If you are implying that CrapMAME is bullying you, the page is static and hasn't been updated, so that removes the "repeatedly" prerequisite. And again, you aren't personally identified.
Cyberstalking is the use of the Internet or other electronic means to stalk or harass an individual, a group of individuals, or an organization. It may include false accusations, monitoring, making threats, identity theft, damage to data or equipment, the solicitation of minors for sex, or gathering information in order to harass. Can't help but notice the whole "making threats" thing again, even with that I'm not sure how much of the law would be applied to trolling.
Couple allllllll that with the fact some of the people you'd be suing may not be American and subject to our laws and things get flimsy. I'm pretty sure suing anyone on here or Saint directly would break the a couple forum rules and therefor would subject your account to be banned. So please, do try.
And just for clarification, when you say anything that involves you "knocking someones teeth out" that's threatening them, you cant hide behind semantics. Lastly, I've already made a full site copy of crap MAME, I really hope you can get it taken down, so I can have it hosted in a country that doesn't have diplomatic ties to the US and I'll put it back up. Getting something taken off the internet is like trying to get pee out of the ocean.
