Tom, I wouldn't get overly excited unless you actually did it. While it is true his site can gather certain info about everyone that visits it he will have to go to quite lenghty means to get your name and address or even your email address. He will have to contact your ISP (internet service provider) and convince them beyond a shadow of a doubt that you did do it. Even then they may not give him any info without a court order to release the information from thier logs as to the fact that you did in fact visit his site at the exact minute the incident happened and that it was actually you and not one of many others logged on to his site at the same time who did the deed. click on this link for more info on just what is collected by an internet site holder. If anything did happen to his site it was done by someone with more than a basic knowledge of hacking 101.
