int, when detected, already received escalated punishment of 14 days on first offense ON TOP of the LP loss. Problem comes when normal players cannot tell the difference between UNINTentionally feeding and INTentionally feeding.
Legitimate afk reasons exist (internet company pooped, power outage in your area pooped, your mom accidentally cut herself while cooking your dinner, etc.). Should these people get significant penalty for doing the right thing and leave game to put bandage on mom's hand? Also, it be open season to flame and abuse teammate so he will afk just so people can selfishly take less lp loss.
