Whatever the reason, the offer differs from earlier ones in many aspects, and it seems that the scammers have pulled all the stops and have decided to take everything they can.
What does the script actually do? It invites all his friends to join a Facebook group.
Once he has done all this, he is asked to prove that he's a human by taking a survey that will also make him eligible for winning an iPhone or iPad. But, in order to enter in the competition for the wonderful prizes, there is another hurdle the user must cross: sending an SMS to a premium rate number, giving up his phone number and carrier and signing up for SMS marketing.
This scam has been cleverly designed to milk the most out of a duped user. A filled-out survey? Check! SMS to a premium rate number? Check! Phone number and carrier information that can be used or sold to other scammers? Check! And in the end, the users is none the wiser as to who is stalking him on Facebook.
