Contact a mod...
They can try to talk to these players or at the least completely remove what they've built.
The player's things (assuming mod does it correctly...) will be saved, removed and/or reassigned.
Chests would be saved in database under the owner of the chests' names. The players can get their stuff back when they find a new place, /sethome. and with a empty inventory use the command /recover to recover all their stuff from the database or recovery. This is assuming the chests are [private] ones.
The structure they have built would be rolled back to a previous date, in this case. Before it existed.
At the same time the mod can remove the player's permissions from the selected area, so if you or anyone else who try to build there in the future will not get banned by the anti-grief system.
