There seems to a be a fundamental issue here with some people not understanding what Mayday actually means.
It is a condition of being threatened by
serious or iminent danger and of requiring
immediate assistance.
The fundamental reason for having to hold a radio operator's licence is so that we can demonstrate that we know how to handle messages appertaining to the safety of life. ITU Radio Regulations Art 35.
So if you have a licence, you should know what it is and how to deal with it.
Will the RT police be round to have a word?
Some years ago we had IRIS who monitored RT standards but now its more akin to Slack Alice. I recall hearing a Military ATCO ask a pilot who called Mayday on running out of fuel on final "Is this a real one or a practice!"
