For reference from the rules:
Do not cheat to get achievements or to mine blocks. This includes client-side scripts, mods, transparency texture packs or any other way that gives you an advantage over the standard and intended game play. I know its hardly possible to check on most of the things, so claiming that you are using such is already worth being banned.
