I propose that we allow griefing of all kinds in the Nether, though perhaps disable TNT there so it doesn't get out of hand.
Currently the typical griefing rules apply which mean only the most valuable resources can be stolen. I've noticed a number of enchanting stations complete with bookshelves lying around in the Nether and I am only allowed to steal the enchanting table. Unfortunately at this point the bookshelves are actually more valuable and I would like to be able to steal them. Considering the nature of the Nether and how often it resets I don't think people should have the safety to leave resources lying around anyways.
