So our skye started throwing from the first round itself, giving spike and our locations to enemy team and flashing us. He did this so that he would get yt subs from the enemy team, he has said all this himself in the chat (local language though).
Is there any way to ensure that this guy is actually reviewed since there is considerable proof that he was throwing? I read somewhere on this site that apart from in-game reporting, there is also some riot site where we can report? Please share the link if you have it, thanks
