at this point i don't think it's advertising or even human verification, more like Lexus torture. I don't even know what I'm gonna do next time I see a lexus i RL, I hope I don't flip out too bad.
if you have enough BTC, come to the premium member's world, the captcha is much easier, it is one of those mini games where you mix and match stuff.
and you randomly get free referrals too
I already have three.
which also brings this question: do I keep the referrals after my premium membership expires?
