Tracking Spammers: Using DeJaNews
Using Deja News to track spammers can be both fruitful and interesting.
Because DejaNews indexes the complete text of all the new group posts in its archives, you can search on whatever telltale bit of text that may appear in the spam. Especially useful are clues such as signature lines, a city and PO Box number, phone numbers, etc. Any of these bits of information can be used to help in identifying a spammer.
From the DejaNews web site,
http://www.dejanews.com/
Enter the name, mailing address, or any other potentially identifying bit of information you have regarding the spammer. You may find other spams sent by the individual, or you may come across another spam-tracker such as yourself who has already positively identified the person behind the spam.
