Don't know bout you guys but the vibe of it reminds me of those fake giveaways where they ask to send an xx amount to the address you see in the screen. And why they mentioned bitcoin.org there. Was it their sponsor?

But, I am sure that it's like a ptc, paid to watch site, or some kind of a faucet where you can earn tiny amount of coins but it sounds like it was too easy for them to collect coins on that site and if ever someone earns from that site, I don't think they will just deposit in a gambling site but they will value it due to the amount of effort they put it. Withdrawal limits and as well as kyc are also normal on all gambling sites.
