@Riot The Dead can't talk.

So, in my experience, most of the toxic comments, are from the summoner who most recently died. I mean, sure, there are those games where Ashe dies and everyone starts harassing her with ("this adc" and "omg" and "gg" and "report ashe"). But realistically, in my experience, the most toxic comments, most of the time, come from the person who just died.

One thing that actually annoys me about W.o.W., is that when you die, you cant chat while you are dead. However, in that game, it is not even competitive, and the chat is almost never toxic.

Anyway, why are the dead even allowed to chat in League? I mean, the dead tend to be the source of the most toxic comments. So, don't you think it would cut back on a huge portion of toxic communications (or at the very least delay them long enough, to defuse the situation so that people might be calmer by the time they revive, which might reduce even more... either way, you are looking at a significant decrease in toxic chat communications if you simply remove the chat option for the recently deceased.)
