According to the 11PM news here in LA... Internet chat room under age hook up schemes are typically set up by older imposters trying to bait and sting.

Those freaks need to get a life, and stop playing vigilantees!

The only thing gained by sting operations creating fictional situations for others to play out in is that fiction is stranger than truth.

If someone IM'd me and said they were 13, I'd double or triple the age, and attach the face and personna of a bitter, unhappy in life and love Bitch.

Of course, that would be after closing the IM window without further conversation.
