The PRS handled it very well. They put the unvarnished facts out that left no doubt as to what happened.
Personally, I'm not surprised to find out it was happening. I've seen first hand how a few individuals will game stages when they think nobody is watching or is there to stop them or they interpret a COF to their advantage after they've been clearly told otherwise in the match brief. I view them all as forms of cheating, it's just a lot harder to make an excuse for editing a score after the fact.
