Whether or not they found it is a different matter than whether or not they feel it meets guidelines or is a good idea for a cache. So I don't think it's hypocritical.
I wouldn't have a problem with the location, personally, but I don't cache with children in tow.
I think the way some are handling it with you isn't very nice - why not send you an email and say "I think your cache page needs a 'not appropriate for children' attribute, and a more explicit hint about the, well, explicit nature of the site?" Or if they feel they must do something public, then post a note, an angry, scathing found or DNF log, or whatever. But I don't think this type of location is against the guidelines, so multiple "NA" logs seems harsh.
I can understand why someone with young children might not want to find a cache at such a location. I hope it survives the NA logs.
BTW, some of the logs for this cache are just hilarious, both ones that didn't like it, and ones that did:
Too funny!
I just wanted to thank mr benchmark for his statement " I think the way some are handling it with you arnt very nice"
The one Cacher in particular sent me a very nasty private email. I was floored.
The cache is temp disabled for maint- replacing with a new container tomorow. So all those who are not offended by an innocuous clean parking lot will be able to search again.
