Update. I know who powerreviews is not and how they got my info. They are a payment part for an MSC. I've gotten several payments (valid) from them for work I did for an MSC. Still not comfortable with them asking for info, but they are a research firm too (based on what I googled). As for the paypal part of it, they have that info. That's how they pay me. But anyway, because there's a "dimly flashing red light" in my head, I'm gonna pass on this one.
