I’m having a bit of trouble buying this outright. Do you recall our conversation opener?

[19:26:48] [CHAT] [me -> KnightofDoom_ »] I am going to ask you to be honest with me.
[19:26:52] [CHAT] [KnightofDoom_ » -> me] yes
[19:27:02] [CHAT] [me -> KnightofDoom_ »] Do you use any mods on your client?
[19:27:28] [CHAT] [KnightofDoom_ » -> me] No, i do not. That would be unlegit, and I like to play minecraft like everyone else.
[19:27:54] [CHAT] [KnightofDoom_ » -> me] i do not use mods. The only time i have ever used is on private servers.

So either you lied or did not understand the question. Either way it seems you know you are breaking rules by your response.

This is usually cause for a permanent ban if anyone doesn’t already know this. Your later admission to using Wurst combined with the screenshot provides evidence; however, had you refused you would be banned for not following instructions.

I’m always sad to loose another player. This is the no-fun part of being an admin :/

I hope this is a lesson to anyone else who runs a modded client.

My advice KnightofDoom_, uninstall that crap, run Vanilla, and enjoy a level playing field. It is better to loose a fair fight than to win by cheating.
