This IOC has created a system designed to produce this effect.
If they don't like the effect, it has to be solved at the system level or it will continue to manifest. If not, the result will be:
1) Players attempting to throw matches with more subtlety.
2) Officials disqualifying or sanctioning players based on misinterpretations of vague, non-verifiable player intent.
Neither of these situations is ideal. It's a simple problem to solve too, -they just need to do it.
