Lland claiming and chest locking is probably a good shout, usually those types of plugins allow you to disable explosions breaking them
Lyou could also look for a plugin that whitelists blocks to not be breakable by explosions or something like that
Lif your constantly having to rollback land that was griefed, then preventing those types of griefs is probably in your best interesting
Lif your players are still getting griefed even with these existing then you should probably stop rollbacking the area and telling your players to use the tools youve given them to protect their land
Lthen just stop doing rollbacks
Lclaim blocks being rare is shooting yourself in the foot, or you simply dont do rollbacks and if your players complain either tell them to claim their land or dont be stupid and build a house out of diamond blocks in an unclaimed zone
HMy server doesn't have land claiming/chest locking, so I have to do it manually
HIt only really works with a bunch of time/effort, and when we can make sure the items that were removed are out of circulation so to speak
