Yeah, you're right about FB being another dating site. That's why I only add people I know and even then you get them coming on to you saying how they have always had a crush blah blah blah..
You know anything goes these days with the internet, this place is also used to hook up. The guys and gals on here are always flirting with each other and PMing, getting personal. There's some weirdos here who convince themselves that there's more to it too and fall for woman on this site...seriously deluded!!! Stalkers!!
