Sometimes all of the offers don't approve, but it only happens every once in a while and on all of the offers they tell you the approval rate up front. Also once you earn $10 on their site [which I did in a few weeks] you can complete manual offers that always get approved. I definitely wouldn't call this site a scam. Yes sometimes the offers don't approve, but its not the majority of the time and I bet if you only did the high approval offers you could easily get every offer approved.
