A few weeks ago a close friend sent me a message on Facebook asking what I've been up to, and I told him about the startup I am working on.

As soon as I hit send I was hit with the impulse that I shouldn't have sent those kind of details over FB messaging -- thinking back to warnings such as (http://www.youtube.com/watch?v=2cdrCYrZIvI).

And sure enough a day and half later I received an email from a Facebook recruiter wanting to talk to me about a job.

Normally that would be fine, but the timing is so suspect. I asked around if anyone had heard of FB mining/reading users messages, and no was certain but reminded me that the FB privacy policy states that they own your data and an ex-FB employee said that many engineers have access to the DB.

Does FB mine or read user messages, and why doesn't it do more to prevent so many engineers from having access to the DB?
