They send you fake "offers" and emails claiming that someone gave you a gift. If you visit the site to try to figure out what is going on, you find it is nothing but an invitation to join. There are no "friends" or "gifts".
If you try to use the link at the bottom of the email to block them ("click here to block future emails") you will find that you get sent to a page where you are agreeing to their terms of service. They are signing you up without your permission and they will not remove you!
