1. You were warned last week about this. You may have not paid attention to it, but you were absolutely warned about it.
2. If you look at Global Rules 5.5, it states "Do not use an alt account while you have another account connected. This includes unlinked bedrock accounts, unless you are in the process of linking them." This rule has been in the rules page for a while now, and has been enforced as such. It is your responsibility to know the rules.
It doesn't matter if the account was purchased by someone else, you're the one using it to alt. Sorry, but you will remain banned.
