Account banned but different person

I got banned in Fifa 17 for buying coins. I bought FC26 on PC and logged in with the same e-mail which was banned. So my new account got permanently closed again. My appeal got denied and I have to accept the fact that it won't open. 

Unfortunately my brothers account (who had bought the game right after me), Is also banned. He did nothing wrong, but EA probably banned it because he linked a twitch account of mine to his account. He did this to redeem the FUT Objective reward "link to twitch to receive draft token".  Because he does not have twitch himself, I gave him my account. Unfortunately, my twitch account has the same e-mail address that was banned in 2017. So his account is probably banned because of that. 

I have made appeals, but there will probably be no succes. Now my question is, will my brother be able to buy the game (for the 3th time....), without getting banned? And is it plausible that EA will overturn the ban for my brother?

It is unfortunate that EA does not specify the reason for the ban so you can alter your behavior.
