People fall for worse scams everyday. I agree w/ you about moving it to the Scam Accusations board though. I didn't know that there was one, otherwise I'd have posted there.
i think people fall for it because the scam is new they still have no idea if its legit or not , moving this to scam accusations is a good idea to inform users , generating 0.3 btc in 15 mins is insane cautious users will surely avoid this new type scam
