Ah I can see why you'd be all weird/anxious about it.
I haven't actually found any of my mates or other people I know on there yet, a few of my mates are whores too so I would've expected to see like certain people haha but nope.
But yeah I saw a profile of my step-niece and oh my god it's odd, I watched them in nappies now they're fecking all adult and shit with pro eyebrows!
I'm kinda not too bothered if people find mine via dating sites, I don't put anything whorey or out of character for me online so s'all good.
Facebook is a bit of a turd but I have 3 of em, one with a fake name, and my main one just has only the first name.
The fake name account I just add internet people who I'd likely meet up with, the other is just like everyone and the 3rd is family only.
With it organized like that I don't have to worry about what I say on my statuses, IE swearing cause of old people etc.
