Agreed, for the most part. I had to contact SuperRewards for each and every offer that I completed, before they acknowledged it. To their credit, they _did_ acknowledge (and credit) my efforts, and did so quite promptly. In the end, it's not worth the effort - especially if I have to contact them every time I complete an offer.
Nonetheless, I have a bit more than 0.1 BTC actually credited, and appearing on the freebitcoins.betcoin.co site; but they're not paid out yet, and they have no way of contacting the site directly.
