Tried logging into www.dollarrewardz.com for (I think) a second time, only to be greeted by this charming message:

Error!
Your account is currently marked as "Cheater."

I am also locked out of my account, there is no link/suggestions offered by the site about what to do next.  Presumably someone in this situation would have no way to redeem payment for the work they have done, in which case you would get to keep any unclaimed rewards?  For all I know, your site could be perfectly legit, but I hope you can understand why this sort of thing might make people suspicious of a scam.
