Do people even get punished for feeding?

With one look at the posts here we can see that the community has a problem with people being "toxic". I'm not sure how everyone else handles it but its really not a big deal at all. Just mute the guy and play the game. The problem here is that the people getting flamed do not mute the flamer and then blames their bad performance on the flamer. Then the flamer because "toxic" get reported while the feeder continues to feed because now his terrible performance is because of someone else. It then becomes, "Im throwing the game because this guy is toxic". The main issue here is that the person being flamed could have just muted someone and still played but instead is now throwing the game for 4 other people. We can all guess what happens, no surrenders, constant flaming and wasted time. Then when we get out im sure the flamer will get reported but the feeder will walk free. So in conclusion, feeding affects 4 people, cursing someone out affects 1. Who is really to blame here?

I'd take a toxic player that carries the team over a feeder that finds excuses any day.
