Okay based on this review alone and without your POV
i am going to uphold the admins decision
he was killed in ghetto on top of the roof and you waited for him to jump down before sniping
you knew exactly what you was doing considering they was still in the area
You have just admitted that you wasn't really there and was pressing buttons to make sure your character didn't fall asleep
so you are technically stopping yourself from going AFK
Therefore an ANTI AFK Action
as Fish already stated the admin made the right decision
