Hello,
Your nether mining wasn't what initially caught our attention; it was the large number of diamonds in the overworld you had mined. A keen eyed moderator did a quick check, as they would for any suspicously large number of edits, and raised it to the admins attention. Cheezy and I then found multiple examples of obvious xray, which you can see on the screenshots in this link https://imgur.com/a/iDcw8u0
While investigating this, we noticed you were online and teleported to you just as you entered the nether. Knowing what you were about to do we watched as you drank fire protect potions, jumped in the lava, and swam entirely under the surface straight to 4 netherite blocks. See evidence of this on the screenshots on this link https://imgur.com/a/mQE3I6g
You were not half on the surface and half under the lava for the majority of your mining session, and even if you were, you should not have been able to see under the lava. See the image in this link for what you should be able to see when doing what you showed in your screenshot https://imgur.com/a/f5KBFcU
I would also like to add that you had recieved a note after being warned about using exploits to traverse spawn. While this had no bearing on the ban descision, i feel that it is worth mentioning here.
Using xray, exploits, or mods to gain an unfair advantage over other players is not allowed, and your screenshots clearly show your client has a function to disable fog to see under lava. The ban was not unjust, it was entirely deserved. The punishment is a 1 week ban, and all your edits have been rolled back, as per our xray policy.
Please reply here 1 week from now confirming that you have read our rules to be unbanned.
