How do you check who's been checking your facebook profile?

Everybody swears you can't do it but I'm not so sure because of the "people you may know" list. I know some of the people I've checked out in the past, even people I have nothing in common with or have ever e-mailed show up in my "people you may know list". Obviously that means Facebook knows I searched/viewed their profile. The million dollar question is am I also appearing in THEIR "people you may know" as well? We had none of the same friends, cities, workplaces, education, etc and I never linked my email account to my profile. The only way it could have connected it is that I once searched and viewed their profile. Even more suspicious is the fact that facebook never really tells exactly how this function works—they say common friends, workplaces, education...AND MUCH MORE. Question is, what exactly is the "much more"?

That said, even if there is a 100% guaranteed way to see who viewed your profile, if they keep making new ones up it becomes hard to confirm it's them.
