You should get your own alt. It is your fault that you left your mc open or did not just make a new password.
What about your brother is keeping you from appealing? Seems to me that you should have not downloaded the illegal mods or just make a new profile that is illegal mod-free. Do not blame your brother for things you could have prevented.
His appeal has been denied. Your account, your responsibility. If you wish to continue playing on EMC, I advise you to buy your own alt.
i wonder if it was his brother using his account when the account was banned for that same thing 9 months ago. and you were given a second chance after that mess up too =\
Do not go about asking for the account of someone else. Your failure to maintain basic security of your account has brought your downfall.
