Who is he? His MO? Does he work alone? Is he part of a group that scheme and attempt to defraud others of their investments?
Is he a wolf in sheep's clothing?
Does he gain the confidence of others and subtly direct them in their thinking and deeds to attain his and ultimately the group's goal? Does he do it by saying or implying that a) he is a long term investor? b) should sell now and buy after price go down c) he is a guru and you should do what he says d) he is down to earth kind of guy and wants to help you e) all of the above and more by cluttering the message board with same old things and plenty of "kukai"?
Is there such a person? Is there such deceit that lurks in the stock message boards?
