I don't know all the details and I am not truly understanding your story, but I will add my input. When someone was caught hacking, whether in FGunZ or another game apart of the community, they were banned altogether. Mindset being, if you hacked in this then you would hack on the next. Also being a donator doesn't excuse you from this rule at all, nor give you any power to bend rules.
Again I can't really understand what you are saying, but if you hacked on the Freestylers Minecraft then it doesn't matter. If it was some random Minecraft server or your own, then obviously you wouldn't be banned.
