How can you?
 

Make it so ur ISP Address is hidden, so i dont end up with a lawsute a month down the road.

personally i think you mean you ip, and you cant hide your's its what the network uses to identify you, but you could dl a copy of peer gardian 2 from www.methlabs.org i think is the site, and it blocks known ips from accessing you, your best bet is to searck the forum before asking questions like that around here, most of these guys arent flunkies, many of them are software developers and programers and wouldnt bother with a question like yours, like i said search adn ye shall receive more information than you care to read
