There was a games survey in the news links a few weeks/month ago that had a drawing for those who entered, and I think it was for an Amazon giftcard.
Whoever authorized that crap needs to be fired. The way that BS was handled I would expect from a noname fansite looking to rip people off, not from ZAM. After you filled out the survey you then had to categorize a bunch of games in whatever way made sense to you, yet the categorization UI was complete crap, and the submission process timed out every time you went through it, forcing you to email another company with the results. It was so poorly done I honestly though it was a scam when I was done. The fact that this person's being asked to confirm a mailing address for a digital gift card code just adds to the suspicion.
