Just because you have a problem with "that sort of thing" doesn't mean to be so...
I've got a friend - a former police officer - who used to do just such work. He would sign in with a name implying he was a young teen girl, and he would get hit after hit - just left and right.
Yes, you and CJ are correct in upbraiding me for being a mite too careless -- in this case I'm speaking to philosophy, to a ideal. The reality is that men who chat-up with "young hot things" on the internet or on phone chat rooms can and do find themselves in lust with a police officer and the fruits of that lust are jail, fines and all the distress the prosecutor cares to throw.
Hey, I'm even, at times, for that in some regard -- I remember when some dweeb tried chatting up my 14 year old daughter -- which I caught using SpectreSoft. Yet -- what did I do then? I told her to stay away from such chats with strangers. Yet in the bigger picture, I can't justify entrappment, "virtual" victims, even in such cases as these. The remedy is otherwise --raising social expectations, and giving the victim's protections, besides such stings using fake victims.
