Next you are going to want people to stop cutting limbs out of trees cause they don't have the proper skills to back into the spot. Or maybe have people stop putting nails in trees to hang laundry lines, or lights. And don't even suggest people stop the clandestine activity of slowly draining their grey tank into the bushes between campsites with a garden hose. And by all means don't ask them to stop leaving their trash inclusive of baby diapers in the fire pit.
And I agree at campsite: No digging allowed you can not fix a hole made in well packed dirt.
