@Riot, can you please add this kind of afk detection system

I have a simple 3 flag system that would punish a lot of afk players that manage to avoid the system.

Flag 1: AFK being stated If a player says "afk" in their chat, this gets trigged or if another player says their champ name or summoner name and "afk", this gets triggered. A lot of players will just striaght up admit they're going afk cause there isn't a real punishment for it.

Flag 2: Going Idle If a player doesn't ever leave a set amount of area (let's say fountain size) for a set amount of time (I think LeaveBuster does 5 minutes, but I think 3 is enough), then this flag gets triggered. It's ridiculously easy to just move a step to the right and stay in fountain to avoid triggering LeaveBuster but still screw over your team without getting in trouble for it.

Flag 3: Getting reported for AFK If somebody gets that check box marked against them in the report screen, this flag gets triggered. Obviously, the system should take into consideration whether somebody's experience was ruined by the afk.
