Girl I used to work with six years ago is on my 'suggestions'.
I have nobody from said workplace on Facebook. Neither do I have previous employer's name on there.

She's married with a baby; I am neither (well sort of one but let's ignore that, Facebook doesn't know).

HOW?? This is scaring me. I do not want a bunch of shitty-ex colleagues creeping up that I have no interest in (she's lovely, but this is why I'm not adding her).
