Since this thread is already bumped, I must say that I agree that TokenAds is a scam. They don't pay you.

The best survey providers for desktops are SupersonicAds (recieved 215 Tokens until now) and SponsorPay (recieved over 75 Tokens until now). The same goes to Peanut Labs, but it's hard to qualify there, however I managed to get be qualified for 5 surveys, Tokens between 7 and 58 for completing each.
