This user was determined to be ineligible after an investigation that discovered that the account in question was cheating, and in violation of our terms of service. As not only the Community Manager, but also the person in charge of Prize Fulfillment, I can say with absolute confidence that we are not, in fact, a scam. I send thousands of dollars worth of prizes out each month to winners. Sadly, some people are disqualified sometimes, for a number of reasons, including cheating or attempting to use multiple accounts to circumvent our per-account prize limits.
The user making this complaint, in fact, had previously won $150 at amazon.com, which she received via e-mail on 11/09/2007, and should know full well (having already received a quite substantial prize from us in the past) that we are not a scam.
I would also like to point out that our service is FREE to our users, so if we WERE a scam, it would have to be one of the dumbest scams I have ever heard of.
