i think not allowing cracked players on this server is a good idea and will benefit the players in a good way. for one, it will allow less troll to disrupt the players in the server and allow players to play freely without having to worry about spammers or griefers . Also, having a creative server and a survival/towny server will rise the servers chance of getting new players and allowing them to chose which mode they want to use. Players dont just want to play/build in survival, some players like to play/build in creative because its much easier to go around and it will maximize what blocks they can use to build there building or games. other players like to challenge them self and survive to the fitness.
