I was banned because of my little brother

[LT_Archangel]

So when i came back home from work i see my little brother still on my computer playing Nord Invasion. He told me he was playing on my archer named "LT_Archangel" and he also said he got banned from an EU server. I had a shit night at work and now i had to deal with this. I don't know why he was banned all he said to me is that he was trying to "defend" himself from the insults that other players said to him. I could not be bothered with his excuses so i banned him from my computer. I was wondering if i could be unbanned from that server and i would like to apologise for this huge misunderstanding and also for making such a risky choice to let my little brother use my computer since i did tell him he can before i went to work. This mistake will not happen again and i'll make sure he won't get on my computer next time.

Thank you.
