I would agree with this to a point.
However, if someone has made a legitimate attempt to solve a puzzle, has driven for a few miles on a seasonal road, hiked (or worse yet, bushwacked) a mile or more up a steep hill, then searched for a half an hour (ignoring the couple making woopie in the woods), asking for a coordinate verification (assuming one has phone service from the cache) via a PAF is certainly understandable.
Last weekend I went out with a couple other cachers to search for a group of caches in a nearby forest. One was a puzzle cache that required a short drive down a seasonal road, then a .3 miles hike up a steep hill (rated 3 1/2 stars for terrain). We were only the fourth this year to enter a log for a cache that really wasn't that difficult. There have been no DNFs logged on the cache either so I suspect that most won't even make an attempt on a cache that has a difficult puzzle and a high terrain rating.
