You can calculate their participation in a game, in fact, the game already does this. Someone who is inting will have very abnormal stats for the game, sounds like a red-flag to me. The worse case would be a false-positive, but if their pattern of behavior is so bad then they should be removed form ranked games anyways.
People are able to work around that. That is why you have players like a Zed Support managing to go through 2 months worth of Ranked matches doing nothing but trolling and inting, yet still manage to hide under the radar.
For instance, had a game where the enemy team had a Disco Nunu. First thing they did was walk straight and die to my turret. After that, they consistently walk into every fight, do like maybe 1 autoattack or non-ult ability, and then leave their team for dead and run off.
Whether or not their team got a kill, the system will think Disco Nunu is still participating.
This just makes Rito to throw the, "They're just having a bad game" excuse.
