This guy spammed the forums with one of thoes "turn $6 into $6000" spams, the words above are mine when i edited his post...
In his spam, was his full name and address (to send the $6 too), i can also track his IP (unique address of each user on the internet) right down to the computer he is using to post the spam. With all this info, i sent the spam to his ISP (A cable company), its upto them to kick him off there service or not, usualy wont happen, but if they get enough reports of abuse, it will.
