He's not "this Shayne person." He's Shayne Heffernan and, posing as Capt Jack and formerly Sean Lee, he is the largest single shareholder in the company, is the mastermind of this scam and holds court every day in the super secret buzz chat room that is allegedly for BZTG shareholders but really is restricted to only a few large shareholders where he continues to work them with his lies.
So, please don't attempt to diminish Shayne Heffernan by referring to him as "This Shayne person." He's the puppet master of this con, nothing less. He's also an internationally exposed con man FWIW.
