Annoying Message that randomly pops up

I noticed that few times today that randomly during games I will get a LoL Client message saying "Are you still here?" or something to the effect and this will cause the game to minimize and you have to respond to it or you won't be able to return back to the game. Like wtf is this Riot. YouTube already do this when I listen to a playlist of music without switching the songs myself after a bit. I'm like "WHY WOULD I BE USING THE CLIENT IF AM IN A GAME!?!??!?!" and this happened total of 3 times today out of many games today I played so its not constant but still this could easily kill someone if they are in a important with a sudden "Are you still here?" :|
