"First of all you can ask the people on the server and I honestly believe that they will say I am a fair player."

This is in no way proof of legit gameplay that claim can and has been used by many,weve had long time players xray and other peoples vouches mean absolutely nothing in the end,people always put up a facade.

"I dig randomly: I get to level 5-16 and where I swing my pickaxe I mine. I do not have a specific pattern. I only go out and dig a hole then go in whichever direction possible."

It wasnt as random as you say, there was a few instances where you dug straight down directly to a dia vein and while suspicious in itself i would gather more proof to be sure,you did dig "randomly" when underground however you went back through your tunnels and then dug directly to some of the dia veins as well as some that i planted there myself to make sure.

"I died many times because of lava, and from what I understand, xraying shows you the lava somehow, so logicly, if I were xraying there would be no way on earth in which I could loose twice my op pickaxe."

I personally have seen quite a few hackers do this before.

"(just so you are convinced) just do /co inspect and you will see I ended up mining other ores except of diamonds most of the time"

This is a vanilla server, we do not use plugins

All in all,we feel that what we gathered is more than enough to confirm your use of xray,you were suspected of it before the day i banned you we just wanted to make sure first.

Appeal denied.
