Judging by the spelling it's probably some 12 year old kid fucking about. I like to talk to people I've just added if I don't know them so I don't have to wake up to sexual remarks on my wall the next morning.
I get a whole lot of attention whores, and those damned 'scene kids' that add me and always post things all my wall like "Your pictures make me hard ^o)" and shit. So weird.
But yes, I do have weird people that always try and talk to me on Facebook and it gets damned annoying and I laugh when I get the constant feed of "Hey" in my messages as posted above. xD
I have alot of weird randoms who try to add me on facebook, or people that I meet through a friend or a friend or at a party one night etc. and add them, only to find out later on that they are total weirdos. I just delete them and ignore them for the most part.
My facebook profile is private.
I often have people adding me just to see my pictures and immediately remove me from their friends list after taking a good look.
Don't accept people you don't know then.. I know you probably do because you think the more friends you have the more cooler you are. That is just lame and only idiots think that.
