When I clicked on it I got a security warning that it was not a safe but a fradulent site. Has anyone else tried this and gotten this message. I didn't complete it because it said it wasn't safe to continue.

I have done several free offers but never got the money. I also have tried to do surveys and they tell me I have already done them but I know I haven't. Am I doing something wrong with the surveys and do I have to wait more than two days for the instant rewards?
