Alert Pings. Who keeps pinging??

there should be a mute feature to stop trolls who not only spam chat but then use their pings until they get timed out..

I thought the same thing earlier- someone kept telling me danger- but I had no idea who it was. And the "who" really is important. If my adc says danger, im getting between him and the danger point.. if its a jungler, i'm getting away from the point.. This is a good thing to bring up.

Can't believe such famous game doesn't have this simple, yet crucial feature :(
