I think I found an exploit in this website:

When I did one of those long ass surveys, I kept pressing the "SUBMIT" button at the end of the survey (to confirm that I had done it) and it had credited me for each time I pressed submit. I was like...WTF? and then I checked that I had enough points to redeem for DAO:A. I submitted my claim for shits and giggles and they actually sent me a cd-key the next day.
lol, this site is so fucking buggy. it won't even say that I completed a survey.
and here's the email they sent me earlier
