Can someone please put a stop to Jack Hershey's disruptive behavior. Just look at what has happened in the thread 'Questions How to Get Started Trading with Probabilities', the thread has been taken over by Hershey and his followers by posting off topic. It typifies his behaviour, its selfish and intentionally disruptive. He has done this with other threads to such an extent that some members no longer post on ET at all. Simply putting Hershey on ignore will not stop threads being destroyed by him as his posts get quoted by his followers. The effect is to drown out the original topic of a thread so that those of us who are interested in positively contributing give up and stop posting. Same thing happened some time ago in the thread 'Why Is The Obvious Not So Obvious?'. Surely its clear to you that he is a problem? The solution to his disruptive behaviour is that he should be restricted to posting only in a few threads he creates himself - where he and his followers can post anything wthout restriction. That way anyone else who chooses can visit his threads. Why can't that be done? Or is it the case that he is paid to post on ET. Until I can see that action is taken I'll no longer post on ET.
