I received this email today (twice). From [edit: email address removed]. After reading the contest winner form, I believe this is an IDENTITY THEFT SCAM. There is absolutely no reason why you should have to include your social security number!
Email reads as follows:
We're happy to let you know you’re a winner in the EA SPORTS UFC GIFMaker Contest! You've won a Sweatshirt & EA SPORTS video game which has an approximate retail value of $80 USD. Congratulations!
To confirm your win, please complete the Prize Claim Paperwork and a Declaration of Compliance ("Declaration"). Both forms are available here: http://bit.ly/1lVy5tY
Please fully complete the Declaration and return a signed original to HelloWorld, the administrator of this promotion. You'll find the return information on top of the Prize Claim Paperwork. It must be received within fourteen (14) calendar days of this email. If you do not return your Declaration within this timeframe, we will need to select another winner.
You can expect to receive your prize within 8-10 weeks once we have received and reviewed your complete Declaration.
