I just attempted to verify this myself, but they want my hard earned dollars first. I didn't see any satisfaction guarantee or anything. That already feels like a scam.
You know, if I held an important opinion about something, and there was a fairly easy way to conclusively validate or falsify it one way or the other, and all it was going to take was a couple of bucks, I'd just pay it. Having good info about the world I live in is important to me.
Just saying.
