you wind up filling out order forms for magazines, CD's and DVD's and a crapload of other mindless stuff. You might purchase $800 for the $300 computer or iPod. And the SPAM will flow. I never completely filled out one, but got the junk Spam for months. My son tired and he didn't have a credit card number but his e mail was 99 percent spam for months after that. He asked for a new screen name.
