the free gift sites

theres all these free ps3, xbox 360, wii etc sites.
just wanted to know which one of these are real?
i looked the the giveaway site which had a ps3 that i could get if i refer 13 people. how would i recieve ps3 becuase it aint even out in the uk.
and do i need any credit cards details or anything?

 

Well, firstly read this, then have yourself a nice cup of common sense.

These are a scam; period. Even if they prove to "benefit" you, with all the details you have to give them to actually get your prize will be worth lots more to the company when they sell on your details to "www.free-viagra.com" and the like. As you request more people to sign up, odds are they will and then have their details sold etc.
Win win situation, if you're the company...

Wake up and smell the roses.

Edit: This is just my opinion, but maybe if you stop breaking the rules with your signature then you won't get banned for it?!
