It was reported in their annual and quarterly reports. There is no reason they would say that even if that wasn't illegal. What is way more likely to be happening is that blocks are being taken offline. If you sold 200 rooms out of a block of 400, it looks bad. If you sold 200 rooms but you have limited your number of available rooms to 225, the percentage looks way better.
I mean, I don't have actual data to say that was done at Old Key West, but good luck convincing me the Contemporary or Beach/Yacht have the rooms available, but due to it's extreme popularity Key West is totally sold out other than 2 bedroom villas.
