The following are the addresses you should use when reporting receiving unsolicited e-mail or usenet spamming. Unsolicited e-mail is the equivalent of junk postal mail, getting mail from someone you have not asked to get mail from. Usenet spamming is when a message is posted to many different topic groups at one time. When reporting either kind of net abuse make sure to include a complete copy of the message headers and the body of the message. Just the body of the message is not enough since it doesn't show where the message originated and how it got to you.
