I'm the admin that banned you.
You should never retaliate by breaking the rules, even if it's against a player who broke the rules him-/herself. As stated in the rules, swearing (in general) is allowed, offending other players isn't.
If you have a problem with another player, you should call for an admin. And if no admin is available, you still shouldn't retaliate, besides being against the rules, it's very childish and doesn't help.
I hope you do understand this. Your ban lasts for 7 days, so untill the 30th. If you do understand all our rules and will behave by them in the future, I'll think about lifting the ban early.
