It can be rational to sell your private information cheaply, even if you value privacy
One of the standard claims about privacy is that people say they value their privacy but behave as if they don’t value it.

Cheap CAPTCHA Solving Changes the Security Game
ZDNet’s “Zero Day” blog has an interesting post on the gray-market economy in solving CAPTCHAs.
