i need help,i think there is a bug

i was playing teemo jungle,and my plan was as i watched it on youtube to hide on bot instead farm and kill adc and support i was there hiden,and almost killed support when it came to remake,all automaticly pressed yes,first i thought the enemy team has afk,but no,the system recognized me as AFK because i was teemo and hiding by element of surprise..

i am banned for afk and demoted

i think this should be adressed,that was my tactics and 2 kills was well worth not farming for couple of minutes
