deactivated (not scrapped!) after 1 month inactive?
Well.. Hmmm. Yes, that would probably be best. I'm still not sure if I should totally remove new players if they don't play. On one hand, it's a tasty treat to find one, on the other, it's a potentially destabilizing thing. Also, if you aren't at war with the PD owning player, it won't attack you.
PD Can be defeated, it's not impossible.
