I have some concerns/suspicions regarding you and your brother's bans that need addressing.
How come both accounts were at some point called Ion? Do you guys share accounts or in-game names?
I also double checked, the bans and noticed that, your brother's account was banned 31/03 at 20:17, and then your own account was banned 31/03 at 20:37, I find this way too convenient that your brother got banned, and then no less than half an hour later. You and brother must be seriously coordinated to pull that off.
