How to avoid LeaverBuster "Afk Ban" without playing a lost game

So sometimes or most of the times you will get that team who feeds a lot and the more they play the more they will die and when you open the surrender tab they will vote No. Well it's just waste of time at this point either way the game will end with defeat so you will get bored and feel caged inside the game cause if you leave you get a ban and if you play you will waste your energy and time in a already lost game where you keep defending till they get even stronger and push to your base and there Defeat. So to avoid the LeaverBuster ban and at the same time end the game faster you have to cheat the system if you stay in the base or anywhere in the game without moving or doing anything you get ban so here's the trick keep killing the jungle camps but don't fight enemy players they already fed so by staying away from them it will make it for them easier to end the game.
