Sham Site Is a Scam: There Is No “National Do Not E-mail Registry”

Have you submitted your e-mail address to a “National Do Not E-mail Registry” that promises to reduce the amount of spam (unsolicited e-mail) you receive? If so, you are the victim of a scam, according to the Federal Trade Commission, the nation’s consumer protection agency.
The Web site at “unsub.us” mimics the language, look, and navigation of the Web site for the National Do Not Call Registry, a legitimate free service of the federal government. The unsub.us site is not run or authorized by the FTC.
