Ello, I'm the mod that banned you

First of all, you were not "walking around." I had been watching you for several minutes tunneling in you mines, moving directly from diamond vein to diamond vein, including diamonds I placed that you somehow managed to turn at just the exact block to dig to them.

Cheating in any form, be it an x-ray texture pack or a modded client, results in a perm-bam. Best of luck on other servers
