Why does this guys have bounty on him?

Captured with Lightshot
This vayne was trolling all game we were legit 4v5 he was afk pushing bot all game. He has 500gold bounty as 1/9 adc with 199cs while the enemy adc 5/6 with 250 cs has the same bounty. I mean come on, it was hard to win as 4v5 but i don't get why the enemy is being rewarded for our bad teammate. Why would i guy like that would ever have a bounty on him?
