The problem I've seen is when MAD is applied properly it stagnates the game, small changes at best updates become less involved and interesting...when MAD fails (as it usually does) then either players orders get ignored by the mod to prevent game ending and thus pissing off players, or follows said orders and makes the game end.
Honestly I have never seen a nuclear war in a forum game not cause a game end, even when handled well. But as I said before nukes do exist and can be made so its hard for me to say no you cannot do it.
