SCAM!
Easy sign up, spend hours doing surveys for them - very slow, ineffective way to make any reward points, but then - as soon as you do manage to make enough to redeem they quickly deactivate and block your account so that they don't have to honour the pitiful rewards.
Even when you chase them up to see how they 'justify' this fraud, they ignore your ticket.
Reported to microsoft, and google, and actionfraud andusa.gov.
