Maybe Janice or Nodummy. TB had a lot of information too.
I was approaching it from the direction of Scott Sand and Ingen. He has been prolific since getting out of prison. He either learned his craft from Ribotsky or has become a middleman for him.
He went from Dumbass pennystock CEO to toxic lender and dirty shell salesman. There aren't many in prison that can teach him that craft. But Ribotsky, Cohen & Company could.
