First of all it doesn't matter if your little brother did it, if you want to avoid people causing issues on your account log out when you're not playing as you will be punished if anyone breaks rules on your account. Further more you need to include your SteamID else we cannot identify nor unban you from our server. I do feel that 5 months a very harsh ban time for MassRDM but until you post your SteamID I cannot do anything as I cannot check your ban.
