Well… why would you say it in the first place? It’s likely not something that should be publicly known.
That being said, though, could you explain further how is it unfair? You were the one who said an IP address of some kind, which the anti - advertising filter picked up and immediately banned you for. It’s up to you to make sure that your account and chat stays within the rules of the server.
Do you understand why what you did broke the rules stated?
Do you understand how you can avoid breaking them again?
Do you agree that you will not break the same rules in the future?
Do you understand that if in the future you break any of the rules that you were banned for already, that you will not be able to appeal again (unless the ban was a mistake or due to extenuating circumstances)?
