ibm604 is a master pumper. He likes to have many shit-bird penny stocks at a time and pumps the hell out of them. He knows that out of 20 stocks 1 may turn around and make him money to more than cover the 19 that don't. By pumping he tries to keep the prices up so he loses less on the losers. He disappears on all his losers. And on a select few, he deletes all his posts.
If I remember right, he was pumping the shit out of HMNY (now .0029), UNXL (now UNXLQ .0041), and of course TEUM (now .37). But to be fair---he does occasionally pick a winner.
