Here is an explanation of the options:
1) Leave the rules alone, enforce the COC in P&R, expand usage of removal of P&R privileges be for those who break rules in P&R but not elsewhere.
2) Completely unmoderated P&R. If this happens anyone taking P&R squabbles outside P&R, or anyone talking politics outside P&R will be immediately banned without prior warning. Ban length will start at 1 week and go up in length for subsequent infractions.
3) Get rid of P&R altogether.
