where did that come from?

From what I understand, google ads matches info on blogs for ads. So far so good: epilepsy, procrastination, baby stuff, teaching stuff...relevant stuff.

I just saw an ad that says: "Affairs made simple: Married Men & Women Seeking Affairs Discreet Online Forum. Free Sign Up."

Where the hell did that come from? Pretty sure that doesn't connect to this blog in any way. What the crap?
