Just tossing this out there, don't shoot the messenger.
A handful of years ago, there was discussion in this group about not diving too deeply here into who received/didn't receive HH points for seaplane charges. We know we aren't supposed to receive them. However, they are awarded at times as we've read from various posted experiences.
The thought with regard to limiting comments was that should an HH rep be monitoring this discussion and actually read of people receiving points, then there might be some adjustments made by HH with stricter enforcement. My guess is that there's is no way for HH to monitor content of PM's
Personally, it doesn't make a difference to me ... just passing it along
