Really hoping this is just my overactive imagination. DH recently told me that he's been getting lots of friend requests from women, he doesn't know them and they're not friends of friends so he doesn't know why it's happening. I didn't have any idea either. But after thinking for a bit I wonder if he's used his email (that's linked to his fb) to sign up to a site that's a bit dodgy/porny and it's spam based on that? (ie they know his email from his registration and are trying to getting him to sign up to other things by sending "fake" women's friend requests on fb)
Please feel free to tell me if I'm being barking mad!
