If only this game could detect premature surrender votes because people don't believe in comebacks and teamplay.
Ever had games where you give up first blood botlane, your toplane loses and your jungler just farms? You are behind thousands in gold but you see that top lost only a couple of kills but he is Nasus vs Renekton, you're playing a hypercarry vs Urgot and your jungler is master Yi stacking his feral flare with worrysome speed. Then your team just decides it's lost due to the laning phase loss and surrenders?
Don't you wish you could override their votes and stick it out till the lategame for an epic comeback?
Of course, if you could objectively detect in-game why people vote no on surrenders it'd be easy, but some people also are easy to surrender and condemn anyone who disagrees to a troll. I wouldn't know how you would implement a system against your case but not mine without in-game real-time toxicity detection.
