We do have a very good explanation of the guidelines around trail markers
You will see that key principle is that it is the trail and not the marker that it is important.
So it doesn’t matter what a marker looks like, but the function it performs.
It doesn’t matter where the trail or route goes, it allows you to follow that route and get exercise by following it and explore and see things along the way.
That is how they meet the criteria.
Finally in this forum we dont post nominations we have reviewed accompanied by disparaging comments as it is not helpful, so I have removed the image you included.
