If you're banned, your characters are considered dead. It doesn't matter if they're removed. When you come back it's a new start, thus, new characters, of course, there are some exceptions, but your case doesn't get it.
If you don't' want to make new characters then you don't roleplay, simple as that.
Also, these kinds of things don't need to be in the chat. If you have an issue with what an administrator or moderator has told you, PM staff, don't make a thread in the chat.
