Anyone get gems from any offer on the Wall of Fear? I tried Nielsen Cash and Rewards this seems like a scam I did everything it asked "Sign up, install the app, and send your 1st log of data." and I have not received my soul gems. I have also tried Survey Rewardz and did not get any gems. Wish it was easier to spot the duds/scams so I don't wast my time.
