Indeed they do have a profile on me - a bare minimum, scaped from GitHub. That makes sense, since that's about the only social platform I use, aside from HN.
EDIT: My GMail address has the most amount of information gathered, which makes sense. It's gathered Facebook, LinkedIn, Pinterest, GitHub..
It lists my skills as: firefighting and emergency planning/management/services. I suppose, with a stretch of imagination..
Strangely it only says I work in real estate (no I don't) when I looked up the email address I use for LinkedIn...
