Neutralizing Explosives?

[Servidion]

So I run my own server with a handful of people and I like a variety of things on my server.

One issue I have is explosives. I have mob griefing turned off and that stops creepers, biggolems, enderman, etc from wrecking the landscape (and capital city), but that doesn't stop things like Explosive Arrows from Bailkon's Weapon Mod, and the Ice Beast in MoCreatures, and the Nuclear Gauntlet from Aliens vs Predators, and basic TnT.

I run 1.5.2 and so far nothing bukkit related has been updated so I can't put up worldguard again. Not that it did anything against Nuclear Gauntlets, etc.

Is there any way to blanket-out explosive damage to the terrain?
