Well, you might've forgotten but we have not so I'll share the information we have on it: FatAmber was made by C99999999 in 2014 and was played by him until October 25th 2014. Before October 25th, FatAmber and Tsai were always played from different locations than each others. After October 25th, you purchased the account from C99999999 and started playing it as your own. You still play on FatAmber up to this very day. Beside the log in logs helping us identify who the true owner of FatAmber is, we also have this: Both C99999999 and FatAmber having the exact same date of birth registered.
Right, so it's fair for me to conclude that it was originally C9's account since only he played on it in the beginning, and he allowed you access to it at a later date. So since that is the case and you have been playing on his account all this time, I don't see how the ban that has been applied today is wrong.
It is C9's, please don't try to change the story. C9 played on the account for 1.5 months before you accessed it for the first time. If you try to deny this then I have bad news for you, because I'm telling you literally what the log in logs are showing.
