Dota 2 Intentional Feeding in Ranked (Edit)

I played a few chill ranked matches yesterday and suddenly this soulless wild IO appeared. As you can see in this video, he deliberately feeds the enemy team up to the point he thinks it's unwinnable for us. I didn't really understand his motivation, but this HAS TO STOP. Valve should take this more seriously and permanently ban these intentionally feeding accounts (his name was ROAD TO 0 MMR btw). I know the quality and the editing both are shit, but in this video, it's all about the content. There is also an unedited version of this: https://youtu.be/STDAI3ybttM And because his profile is public anyway, there is nothing to stop me from posting his account link here: http://steamcommunity.com/profiles/76... This is the match ID: 2971749699 Youtube, Reddit...do your thing!
