The AFK problem

The amount of Dc's and AFK's i have gotten between today and yesterday is absurd.. Even more so is the amount of lp i've lost because of it. Currently in a game with 3 DC's.. Riot, i'm begging you at the very least make these kinds of games not count. Like penalize only the DC'd people or something I don't know, but this is making it extremely hard to enjoy the game anymore.
