Maybe, maybe not. HAL has its own private forum that several CC posters haunt (some even using the same screen name) also. Topics and discussions are identical to similar CC, but HAL knows who is who.
On the other hand, some 10 years ago a poster came on CC HAL board and asked a question concerning a family member set to cruise with them who had limited capacities, and within a few hours they had received an email from HAL addressing their concerns and what would/could happen if that person had an issue on a ship.
