You assume the messages are sent by subs. Also, to recieve a message doesnt imply that their must also be a response. If an air unit or non-combatant surface vessel sends a single message every now and then, what risk to they have of being attacked by Allied units. Air units are fast and can go where ever they please, surface and submersible vessels can send and move. My understanding was that the HF/DF was a threat when they were in relative close proximity to the sender and/or when the sender sent a series of signals over time allowing the HF/DF reciever to plot course and intercept.
A single transmission would only give a HF/DF reciever one bearing to use on a big ocean and the sender able to go in any direction at a multitude of speeds...without two or more additional bearings to extrapolate with, you basically have one choice and thats hauling ass along that bearing for a target at a unknown range, moving in an unknown direction and speed away from that bearing. Every minute/10mins/30mins, etc you travel down that bearing without a sighting your odds of finding the target decrease. Also some argue the existance of HF/DF on DD/DEs was overlooked by the BDu/Dontiz for most of if not all of the war. So reports would have been still made, there is no reason to think that some of the those units in game doing the simulated reports werent attacked.
HF/DF is a big threat for those realying continous messages in an attempt to rally others for a coordinated attack, performing daily status reports(so your being tracked from shore over a long period), long messages, or when air units are in the area either being vectored to your area or it has its own HF/DF unit.

With respect to elite DD/DEs...of course there were some well manned DD/DEs in the early part of the war, but I think its been established that most crews were inexperienced with their Sonar equipment and vessels. Most didnt have active sonar, but instead relied on passive sonar if I remeber correctly. I think making all crews elite is wishful thinking(challenging, but inaccurate). Allied crews were "killing" ghost subs for a sometime into the war.
