Solving AFK's problem

I thought of a good way to solve AFK's problem

For example....the system would look like this:

You go AFK a maximum number of times...lets say 10 or somethin......then if you go afk 10th time you automatically drop a division or few tiers.Then it resets and the system starts counting again. I understand that some people go AFK because of net problems game crashes and things like that but the AFK count system would let the player to fix the issues making him go AFK. And by the way the number of how many times you can go AFK can go up and down depending on RIOT's choice...

I will keep thinking of a solution to AFK's problem to help RIOT since we all had problems with AFK's in our matches :)
