I understood that aymen, although you should never insult back whoever insults you on the server, record a demo and provide it to an admin so he bans the person. There is the right way and wrong way of doing things..
Also I am aware of how many chances you have had and what was your offences. This ban will be discussed in an unban panel, the circumstances and the reason behind it.
Note: I don't care what he said in a foreign language, still not allowed, you don't see me talking in my mother tongue.
