I don't know, I still have the feeling your story doesn't add up perfectly. Why would he know your name already if this was the first time he joined the game? Why would that be the first thing he says? But anyways, you're telling me you didn't know him, so let's go with that.
Now, you could have made it a lot easier for yourself if you had just told me the truth from the start, but you kept lying until you had no other choice than confess. You perfectly knew he was ban evading, he even told you himself, but you denied that until I told you what we found in the logs. You knowingly broke a rule, you knew he was ban evading and yet you didn't report and you were even teaming up with him instead.
When we started this server, we didn't keep anyone banned and thus everyone got a second chance. But I also said that we would keep your history in mind. That's why I'm deciding to keep you banned. You got your second chance, and you wasted it. You've already gotten so many second chances, but at one point, it has to stop. You were banned for a year before this server opened, so you were able to play earlier than expected. Now, we're not even 2 months further and you're breaking the rules again. On top of that, when I gave you a chance to explain yourself, you simply lied about it and denied it ever happened. I'm sorry, but you're not getting another chance.
