Hi
I do think there needs to be a careful look at the wording of these emails.
Most wayfinders will not be aware of the existence of these emails, why should they.
So one that is meant to be about “education” and contains phrases such as violations and permanent bans will of course cause stress and worry.
I am really glad that @NianticAaron has been able to quickly reassure you about that. I had one of these emails a few years ago and it put me off submitting for a long time as these sorts of reassurances and examples of the issue were not available. So things have improved but I know how you feel.
With regards to trail markers the guidance that everyone should be following is in the criteria clarification section
The emphasis is on the route or trail as that is the element that is about exploration and exercise. The markers are simply anchors for decision points on the route, enablers of following it.
