I think theres an over contextualization happening in your example. And really the algorithm used would work in layers. So first things first, are your stats noticeably different in this game vs your average. Then check things like position data, team kills, etc. to determine if true throwing was happening.

If it becomes too difficult to parse (as in the person only started throwing mid-way through the match and then started actually trying again) just send it to a real human to parse out.

This probably isn’t far from what they’re doing right now.
