If you are able to install a mod I'm sure you would be able to remove it as well. So I simply do not believe the excuses of your inability of removing a modification. Also a side note is that we say that you are reasonable for your account so if even your brother used it then you will still get the punishment.
Also I have banned your alternate account of dnyates. Your forum IP and ingame Ip[dnyates] are the same and according to you live far away from each other.
