Hey Hey,

You have his IP Address... Resolve it... For example.. Someone with my ISP would have an IP address similar to 65.93.84.XX and when resolved you would get Kingston-HSE-pppXXXXXX.sympatico.ca. You now know that my ISP is sympatico.ca. You would simply have to browse to sympatico.ca (or www.sympatico.ca) and look for a contact us/report abuse email address

Peace,
HT
