It seems to me that if an activator wants to cheat by not being in the SOTA AZ or POTA park boundaries that they could also cheat on this ‘additional evidence’. A photo of my setup - with or without me and the dogs in it - looks much the same at most summits and in most cases would require someone who knows that summit’s AZ like the back of their hand to say if it was there or not - same with a POTA park.
Apparently there are legal ways of establishing one’s location at a particular time but like most SOTAers I hope we continue on the basis of trust given the number of violations is tiny compared to the number of honest activations.
