Start tourney -> VIP all users currently in room -> set maxclients to 1

now only people who should be entering the room in the first place (people who might be pinging etc.) can join, minimising the likelihood of getting the one user who keeps joining on endless alts to flood the room, attempt to crash the room with join spams etc etc.

So I don't think it'll make it harder.

Maybe I didn't explain this one well, /vipall does not auto-vip all people coming into a room - it vips all the users currently in a room.
