I don't know guys... don't knock it...
You could create a small, separate world which could almost be a prison where people can be banished... one filled with beautiful buildings, plenty of diamonds in every unlocked chest... TNT, flint and steel, and fire-spread, abundant throughout the whole world...
And then the world could auto-backup every day, to torment these griefers and remind them how futile it really is.
Oh, and automatically clear their inventories too, so they don't even keep anything, and have to start from scratch each time.
Edit - and in the background there'd be Rick Astley - Never gonna give you up playing on a never ending loop.
