Coincidentally today, I have formed a weird theory about reCaptcha. I created a fake facebook account recently. And every time I try to login, I'm getting verify you are human screen that is Google's recaptcha. And I was solving recaptcha for 8-9 times on some occasions. I think the number of times I have to submit in one session went up after couple of days of Facebook usage. My theory is that, Facebook tags many accounts to be fake internally and instead of banning, they use these accounts for data farming including collecting data through Google's recaptcha (but incentive is not aligned as it would help it's competitor unless there is some payback model). This is anecdotal and 99% I'm wrong. But if I'm on the other side with the incentive to use data, it is definitely one I would try to capitalize on.
