Why do people share hunting reports? I don't really see any point in that, scout reports already show the presence or lack of scattered foes.
Sharing looting reports I get, because it tells others if there's still gold/loot worth plundering. Sharing foraging reports I get, because it tells others if there's still equipment to be found. But hunting? A scout report is both much more revealing and much less spammy.
At most, a marshal could get a summary report at turn change of the likes of "5 nobles of your army hunted in your region, killed 50 enemies and lost 10 men", but I don't really see much usefulness in that either.
