Yeah, I know some people who do that. I think it’s a natural extension of online ‘video’ games, the use of avatars and fantasy role-playing so prevalent in the last couple decades of teen collaborative entertainment. Seems kind of pointless for internet dating; but these are probably people who never actually go beyond virtual interaction on the web. I’ve also known (though not personally) some psycho types who have developed complex, ersatz identities on the net with false photos, faux family members and often work stolen from others. I can think of one woman in particular who posed as an accomplished New York photographer, painter and model and had almost 5,000 friends (including myself) lauding her talents before she was found out and virtually all of the images she had posted of her work and herself exposed as frauds, stolen mostly without revision from others. I’ve also run into several ‘professional’ provocateurs (sometimes known as trolls) who love to go in, disrupt and take over other’s forums and websites just for kicks (before they are inevitably banished). I have to believe that some of these people are seriously mentally ill, although that doesn’t stop them from also often being quite brilliant, fascinating and technically adept (as well as insanely irritating, which is their intention).
