Start banning the consistent AFK folks

My girlfriend has had 3 "20 minute leaverbuster punishments " this month. This stems out after having the 5 minute and the 10 minute punishment already. She afks almost every game. I am using her as an anecdotal experience, but there are PLENTY of people who do this. Enough is enough, people should have a 14 day ban after their 10 minute punishment in the same month. Its not far for shit internet plebs to keep ruining the game for everyone else.
