I know nothing about Shackleford's motives beyond the obvious. He allegedly signed an NDA before witnessing MDawg's play session of baccarat. I do not know why anyone would sign an NDA unless there was some kind of remuneration or partnership written into the contract. Otherwise, you're signing an NDA for the sole purpose of sharing the grandeur of MDawg's presence while MDawg plays baccarat.

The unsettling part of the relationship was MDawg continually saying "verified by the Wizard" in a dozen or more posts. If I saw a dozen, there may have been dozens.
