We can lock doors, chests, trapdoors, and even item frames and Horses. Why not add in armor stands? Armor stands prove somewhat annoying to deal with when griefed, difficult to roll back the armor on them, and can even double the armor stand itself during the roll back process ( It's happened to me ) . Armor stands are good for decoration, but are pretty much grief bait currently. Why not remove the grief bait bit? If it can work on something as simple as an item frame, I'm sure the ability to lock armor stands could be added onto the plugin.
