What about if you made sure you had a private group of 32 players? Can this group be forcibly broken up by the game in this instance? No pun intended. With a fully populated group, no other players could join it, so is a private group overridden by the games desire to push player killers into all online?
Thinking about it the 32 player group wouldn't be able to have committed these "crimes" against other human players in the first place! But say they had a group of 30, did their naughty deeds, and then invited 2 more in afterwards. Is this 32 player private group now "hidden"? The answer may be buried in the DDF archive somewhere.
