I can certainly understand that view and I don't even completely disagree with it. In some ways, it's really no different than participating in a find on a cache that one person in the group has solved or getting the answer from someone at an event cache.
At the same time, though, I tend to feel that not everything in life was meant to be quite so easy. Some caches are deliberately designed to be a challenge (whether that be a TT puzzle or a DAK Girls storm drain or a monumental hike into the Anza-Borrego). Somehow, having the answer freely available on the Internet feels too easy.
I am curious (and I'll probably ask them) whether these folks would respect the wishes of a cache owner who writes to them and asks not to have his or her cache listed.
By the way, if anyone wants help on any of my puzzles, you don't have to go to "Spoilers.Com". I'll help you through it at any level that it takes for you to be successful.
I hope the way I'm doing this quote comes out correctly or else it will seem pretty stupid. I remember just being in the right place, with the right people, at the right time to sign the log for a cache that I would have never found in my life but fate was on my side. I didn't have to solve anything and I wouldn't have been able to if I had wanted to attempt it. We all weren't born Mensa members. Some of us sat in the corner with dunce caps on but we still enjoy geocaching.
