The players have always known this was outside the rules, and only a few violated those rules, perhaps more than the few of which I was aware, but still not many.
I think what's new about the situation is that it has become a more common practice. Now that pool has started to bring its majors to more and more humid locations (World 9ball, Philippines Open, Hanoi Open, just to name a few), there's every reason to believe that the trend toward greater doctoring of the cue ball would continue if left unchecked.
WPA is saying the right things here, but unless they take enforcement seriously, this is all just hot air. You see this as a scandal and I do not, and I really do not care who may have doctored the cue ball at the recently completed World 9ball.
I see this situation as an opportunity for pool to make itself better and I hope it does not become a missed opportunity.
