One of my favorite methods of getting rid of annoying spam is to use throwaway forwarding accounts such as www.spamgourmet.com. This allows you to create as many throw away forwarding accounts as you want, and if one of them begins to receive too much spam you just kill it. Spam gourmet also offers a simple self destruct feature too, where you set up a forwarding address to die out after x email. I can say I am very pleased with this service, and I receive next to no spam on the account my mail is forwarded too. (This is probably not the best thing to use on your friends, but it works for everything else )
