I mean TW did allow chinese admins to ban users during EA so yeah we have seen what a bad admin team can do lolThe only possibly "dangerous" thing I see in a mod being larger than the base game (and servers) is that, if it's the ONLY big mod with big servers, it might at one point be filled with admins who just ban people they don't like - and the banned people might be basically ostracized from the game for no fault of their own.
Example: I remember a relatively large server in the first days of Napoleonic Wars where the admin was a raging racist. And I don't mean some N-words, I mean constant slurs being thrown and absurd tirades in chat about X people being Y. That server went away quickly, but imagine if cRPG would, one day, be in the hand of someone who's like that and there's literally no other server with more than 30 players to be on. Not a good outlook.
