This may simply be an issue on my server, but it should be noted that one may mine redstone with a silk touch pick, replace it, and mine it again for xp and chance for double dropping. This not only unbalances the supply of redstone, but allows a abusive way to level up mining. I checked Lapis Lazuli and Diamond for the same possible abuse, but found it not to be present.
