content: I know it's rhetorical but I'm going to answer anyway.  I had a fake Facebook account for reasons I don't even remember with an obviously fake name and fake location (Timbuktu or something).  Despite all that I got constant friend suggestions for people I didn't know.  On a lark I went through and clicked "add friend" or whatever on a bunch of them.  Low and behold, some of them added me and I went to check out the pages of people who would do such a thing, it was exactly as pointed out (lonely and desperate); very depressing really.
