It looks completely unfair and a bit crappy to shoot the POB of players who largely had little to do with with the recent IMG-Bretonia diplomacy. Understandably, whilst your course of action makes sense inRP, I think when dealing with POBs you need a more open-minded approach since they're a sum of lots of players invested time and roleplay. Indie players being punished for roleplay pretty much exclusively between official factions is hella lame.
