Then you need to muster the necessary support for such a rule change if “worth another shot”.
Under Rules Committee Protocol any GM is welcome to initiate a referendum for a rule change by doing the following:
8.) Any GM in the league may propose a general referendum to be considered by the entire league if at least eight (8) member co-sponsor the referendum. A referendum must receive at least 16 votes to be implemented—this would be a simple majority of 15 + 1.
"Muster up the necessary support" is what I plan to do, but like any rule change, I want some discussion first so I'm waiting to see what owners have to contribute here.
I agree with just calling trades involving these players invalid, as the whole point of the discussion is to make the rules more black and white and that's the best solution at the current moment.
