Which bit of "simple courtesy" don't you understand?
It may have escaped your notice that there are a lot of shooting buts and associated infrastructure on the moors. Now you may not agree with game shooting as a sport, I don't, but letting the farmer know that you are in a particular area might just be a good idea for both sides.
As far as I know, the farmer has always granted "permission", he'd just like to know where people are on his land away from the marked rights of way. If there have been any problems it's because of people parking in front of gateways and preventing access.
