I've heard you can report the IP address as a spammer then all of the spamers email will start getting blocked. This duz take time but will be a pain for the spamer to fix . I Know this can be done because it happened to my friend he got some malware in his PC sending viagra email a while ago. But I sorted it out for him. There alot of info on how to do this just google report spammer

i know all of this will work but in the feild where it says who its from it says my email adress so then i would be reporting myself
