A user can place blocks into claimed area if the block is in offhand. It works with torches, as well as furnaces (Both accidentally placed and town notified), but it seems to ignore the protection.
I had been to /t spawn ishop to go to their spawners for some xp and had a furnace in my offhand, which I accidentally placed when clicking something (I think a sign or something.) I notified the deputy mayor who broke it after I removed the protection. I apologize for my late response.
