Hi TT . . . You are no doubt correct, and I certainly was not thinking about penny pump and dumps when making my comment, but I was focused on real companies that are trying to conduct normal business requiring a fairly high cash expenditure and able to attract investment (as compared to speculation) money. That said, there are without doubt examples of things happening as you indicate. The paid to post pump brigades wouldn't exist and show up for periods on boards if it had not been found influential.
My comment was really focused on the investor with the scale of position that, as a strong hold, could support a move in EXS shareprice, as a real mining explorer. Those I believe will be doing their DD and if they notice or care what is said here they will have enough sense to put it into the perspective of their DD rather than use it as a main factor to form their DD.
