I dont think he fed in purpose. Only 3 of his deaths look suspicious. You can see him trying to escape in most of his deaths and actually escaping a few times.
But he indeed ruined the game by refusing to play with team for more than half of the game-time + taking farm from carries a few times.
About not votekicking him: they were informed, it was obvious that he wasnt playing and the votekick was initiated multiple times.
So:
x3lt1q !banned 6 days + !3 warns [Game ruining - refusing to play]
alice. / caluro !banned 1 day + !warned [Refusing to kick game-ruiner]
!locked
