Addressing players that afk based on how the early game goes

Recently I've been playing ranked around gold-plat. Not every game, not even that often, but whenever I see someone simply afk and stay in base because someone either loses lane, or dcs, I find it is very difficult to win the game. And I have reported numerous of these people, and yet, I haven't received any player feedback report things that show that my team's reports have been getting through. I believe that there needs to be a stronger, more harsh punishment system for players that afk based on how the early game goes, am I the only one?

(note: we never agreed to open in the games I played yet they stayed in fountain and moved around a little to avoid leaverbuster auto punishment)
