Say's a person who's so bitter about his main source of income getting busted.

I do have a question OP, I do see YOSHIE tried to give you a second chance. Why did you go ahead and enroll the same accounts in the same campaign again?

Here, there's no way of proving if it's actually your brother's account or just your other alt so the best thing you would have done is avoid enrolling in campaigns or bounties your "brother" has already enrolled in.
