I'm sorry that you seem to be discontent with the ruling here, however, there is still a case of you using a modified client in order to find blocks, regardless if it truly was X-Ray (perhaps you modified the client to switch every block that isn't iron, gold, diamond, emerald, etc. to be transparent. Furthermore, even if you were conversing with a friend who was depressed lately, you would stop yet have no head movement, as such you would be still (based on how DrCookie claimed you were using xray, you wouldn't have had a still head while scanning for blocks). Furthermore, your threat that controversial bans like this would cost a large portion of the player base isn't going to win you any favors.
