ok so i accidently made a multi on a world. i didn't conquer it or got him in my allience and i told admin to ban the multi colony. he said that it was ok and i wont get banned. then he banned my entire account that had the multi is it possible to just ban colony instead of account?? i already messaged him and its been a day plus i had a rank 6 colony on the account that got banned

To my knowledge, the Server admin has the ability to ban accounts, not colonies. Maybe you could ask him to delete your 'multi' colony and un-ban the account? But really, you were careless not noticing that you were creating two colonies on the same world.. Good luck getting un-banned ^_^
