After a few brief forays on my part into those sorts of worlds, my conclusion is that there are not ANY, not even ONE, real person(s) behind any of the names/monikers/posters. I believe it is almost all 100% computer generated AI garbage meant to facilitate the speedy transfer of money from the honest/naive/inexperienced/greedy/stupid to the account of the Mastermind behind all of it. Not sure who it is, but the investment world would be a better place if he went away forever.
By now you know I am exaggerating a bit to make the point I am making but I truly believe this to be the case. It also would not surprise me in the least that the Mastermind is some sort of dark ops superteam within the bowels of a large legit enterprise with a household name we are all familiar.
.....ok, maybe I read too many suspense, crime thrillers
