From The Washington Post:
The Federal Trade Commission is warning people not to fall for a Web site claiming to offer an e-mail version of the federal do-not-call registry. The “Do Not Email Registry” invites folks to submit their e-mail addresses to stop getting junk e-mail. Trouble is, the site has no affiliation with the government, despite what its Web address (www.unsub.us) might suggest….
The FTC (www.ftc.gov) issued a press release Thursday saying the site appears to be a scam that could be collecting e-mail addresses on behalf of spammers.
