343 Please address H3 modding and fix it

So Halo 3 is now backwards compatible and players are modding matchmaking and getting away with it.

Please make a permanent ban or fix to prevent modding on Halo 3. I know you guys can do it and it would mean a lot to the players who are still enjoying a great game.

I think 343i can not put the banhammer on halo 3 classic anymore.
