Ok if U see some site like http://bitcoinaliens.com/faucet/ and http://litefree.net/faucet U can see that the have a double CAPTCAH, in thise way: U can leave the video how it is and open up anotherpop up with says clik if u're a Human... just an example
Yes I see how it works - I'm just not sure what the benefit from this is? And why would you want to complete 2 captchas?
One ore two captchas is the same for me.... but the people that use bugs have to work more to figure it out....
