Thing is, this "relative" excuse has been used so many times by numerous cheaters who were breaking bounty campaign rules that no one will believe you now , even if what you are saying it's true and your brother is behind that other account. I remember that some even shared picture of their alleged family, all "working" together. It didn't help of course.

It might seen not fair to you, but in 99.99%+ of the chances it is a case a bounty rule abuse.
