although this has happened to us all, it is sometimes a fault of the quick join mechanic and not the player themselves, i feel giving the captain power to deny the right for someone to play would be like kicking them off there ship in lobby, and for that reason i can not ever see this mechanic working, as it could be abused to deny lower level players also and to keep kicking players till there friends name appeared instead. interesting idea for a prompt however but poorly implemented in my opinion.
