Facebook = Big Brother?

OK, I'm officially convinced that Facebook is spying on me. Or stalking me. Or reading every piece of mail I've ever gotten or something. I don't know, they're doing something dammit. Cuz how else would all these people I've never heard of or haven't seen in like 10 years and have never emailed be suddenly friending me?

So I have to admit that I have some friends on my list that I don't know. Like seriously, I have no idea who they are. But that's my own fault. Back when I first joined, I added everyone that added me, even if I didn't know them. I don't know, I just figured I must know them some how but couldn't remember. Like one girl went to my high school, and for the life of me, I haven't been able to remember if I knew her in high school. But my memories of high school peeps are sort of vague anyway, so I figured it must just be my crappy memory and said yes to her friend request. A year later, I still have absolutely no idea who she is, and we've never exchanged a single message, wall post, or anything.

There's also this random girl who apparently went to my undergrad school and was friends with other close friends of mine. No idea who she is, though she does poke me now and again like we're friends or something. I keep waiting for a click of recognition but so far, nothing.
How do I remove these people anyway? And will they know and be offended if I do? Anyway, this isn't Facebook's fault, its mine.

And every now and then, I get some sketchy looking India guy "winking" at me or trying to friend me. Sometimes multiple times, despite me ignoring them each time. I have a good idea of what they're looking for, and I do ignore them. One was a fat guy with a mustache, looking as slimey as all get out. He was wearing a suit, looking off to the side, on his cell phone like he's on some super important business call. I can almost see the cigarette dangling from his mouth. He was from California City -- is that even a real place? Another was a local, more normal looking dude that I tried to pass off on my friend. She politely declined, but then in some weird twist of fate actually happened to meet him in person a few months later and was SO not impressed. These requests aren't Facebook's fault either - seems more like its just guys who have nothing to do with their time but scour through Facebook profiles looking for potential hook ups.

But lately, I've been getting some more random friend requests that I can't explain. People that I'm perfectly happy to see online but don't get how they could have possibly found me. For example, recently an old roommate added me, and while it was nice to add her, I'm confused as to how she found me. For one, my we have no common friends. Absolutely none. We didn't go to school together. We didn't work together. Also, my email on Facebook is an old one that I rarely use except for stuff like Facebook. Its certainly not the email that people mail me at. So the address she would have had in her address book is not the address I have listed with Facebook. And, I'm pretty sure she wouldn't have searched for me specifically. I'm guessing that aside from a few emails, she hasn't really thought about me since we stopped being roommates. I don't know, she was super sweet and nice, but we were just never really friends. A fact that's demonstrated by neither of us having made a single effort yet to actually message each other even after we added each other to our respective friend lists.

So how on earth would she find me? I can think of only one explanation. You know how you can search through your address books for potential friends? And FB tells you they don't keep the addresses? I'm starting to wonder if they do keep them and use them to pop out those friend suggestions they keep sending us.

Either that or they're taking an awful lot of digging into my ancient history, maybe even hired a private investigator.
