I know facebook aint the safest of places but this has me puzzled.

I have had my main account on there for about 5 years now and not really used it heavily, I have 140 friends and probably post once a week.

A couple of years ago I made a fake account in the name of a woman, cant even remember the name but it was as generic as you could imagine. I was spying on my current GF at the time, although I cant remember what I was actually doing. I never did anything with it, just searched profiles I think.
I registered that second account to my hotmail email, my main one being registered with my gmail.

The other day I looked in my hotmail and the female account had a mail from facebook, the mail says the usual "do you know these people" but my real account is listed in there as someone I could potentially know, and the rest of the recommendations are people off my real account, ones that I added a year or so after making hte fake account.

Does this point to any security holes in my PC anywhere?
