'Dutchy' ya don't need to be very bright to drive a plane so hence there will always be an element of Neanderthal types who simply use 121.5 as a plaything
I've had to use 121.5 at the direction of ATC in an attempt to contact a wayward plane out of contact but that's based on an issue becoming a safety issue not creating a safety issue by it's use.
