After my first week of scanning and banning, I wrote up a report on the effectiveness of the blocks." In related news, SSKennel adds that: "The U.S. Federal Trade Commission has discovered (prepare to be amazed!) that revealing your email address in chat rooms can get you spammed. It claims to have taken action against spammers who harvest email addresses and use them to send fraudulent spam." Shocker!
