As Chairperson of the Imperial Reserve, I support this suggestion. @bobman3355 Mwhahaha However, in seriousness, this should never be approved. -1
Well, I have on two different occasions reported serious dupe exploits related to bridges and doors. Each exploit was capable of generating well over 1,000,000 copies per hour.
If I recall correctly weren't those both issues where the blocks could be created by certain interactions between other things (namely water and lava). If such an exploit was generic across all blocks I highly doubt we would still have bridges at all. (this is of course completely ignoring the fact that anyone stupid enough to try this with quartz would be caught and banned rather quickly)
