I don't play in the leagues on here, but in my circle, the cross crease goal is simply known as "The b***h Move" and is automatically disallowed. In the case of disagreement between the two players, a third party is brought in to watch the replay and judge whether it was legal or not. I once had to call a friend out of state and describe it to him over the phone go get a ruling.
When I first discovered this site, the first question I had was "I wonder if they allow The b***h Move?"
