I think the point was, it was a merge. They gave the new leader less power than all the other officers, but enough of a rank that he could set up a raid team (which, to my understanding, is what he promised them.) New lower-rank officer then accepted, and promoted the gilseller-named account to regular officer, or fc master status, that account stole all the money, and then presumably transferred it somewhere and deleted itself.
This is exactly what happened.

The "RMT looking character" was promoted to rank #2, which is an officer with almost all rights. (Used for months only by the master's wife)
