Hello, I am the staff member who banned you.
To start off on my reasoning on why I banned you is really because of your past offences, you've been banned 3 times before I banned you and all 3 were your being retarded and a Minge and 1 was about you RDMing twice again. You also have two notes that are RDM as well. I understand where your coming from on why you killed him twice this time, but you did it twice... You didn't even try to contact staff you just dealt with it yourself, this comes onto the next part I will be explaining.
Let me explain something here.
If or whenever someone says something about something that in the previous life or before they died they should not remember it that is breaking Life rule #2. Since you did nothing apart from shooting him again as no one wanted to deal with someone breaking NLR for some godly unknown reason.
These questions are failRP, anything relating to failRP should be reported to staff. And as such you did not report it you took it into your own hands and shot him instead.
This is breaking Metagame rule #7
Also along with your pictures you provided, they do not matter. If he did or didn't its all OOC unless its in character then its either a joke or an event he is actually interested in.
So in summery on why you were banned and my reasoning for doing so is primarily around that you didn't report it to staff or make a player report on the forums. You desided to take it in your own hands and shoot him, twice I will also say. Now if your gonna make an other responce stating that he was being annoying or being obnoxious then its just failRP, he isn't acting like a member of the KAISERS GAURD nor is he following metagame rules. So let this be a reminder to you, if someone is saying OOC comments in IC then it should be reported to staff as it is Metagame.
That is all I will provide, it is now up to UA's discretion. That is all have a good day.
