JollzTV a popular streamer is doing a challenge where he is going for knife to gold. It's really annoying for a few reasons, it ruins the experience of his teammates who might be losing because of this braindead challenge. And he's also smurfing in iron, while being a radiant. Either way he's ruining the game for someone. You can argue he's using a knife so it should be fair right? Wrong, most players don't listen to audio ques in lower elo so he can just omen tp behind and kill all 4, and when the enemy does listen to audio he's ruining the game for the 4 teammates he has. I don't see why riot allows this kind of content and even invites jollz to events, and riot content testing.
Also to get these iron accounts he needs to either grief games or buy the account both of which is against riots TOS
