Wow. Great conversation here and an excellent problem that needs fixing.
I've been Geocaching since 2008, however, I've only just gotten back into it and only have 10 found caches to my name and I would consider myself one of those "Noobs"...albeme a RESPONSIBLE Noob. I went to the website. I read the rules and treat all caches with the utmost respect and try to leave them better than I found them.
I started geocaching with the free intro version, which I later purchased the full version of, and yes, I used a smartphone. I got back into the hobby due to my recent purchase of a Garmin GPSMAP 62ST. I discovered that when sending the geocaches to my GPS, the descriptions and logs were not available without a premium account. Most times I don't need this information, but I found I could use my C:Geo on my smartphone in tandem with my GPS to get that information without a premium subscription.
Currently, I'd agree that I'm abusing the system in this manner (even though I behave myself), however, I intend on subscribing here directly as I like Groundspeak's easy interface with my GPS and I'd like to phase out the need for the smartphone in the event there is no cell service where I'm hunting.
The problem is with Groundspeak's eas of access. Their database is available to all of these third parties who offer the services and apps for free. Why buy the cow when the milk's free? That being said, I understand Groundspeak's dilemma. Lock up the system too tight (become a paid only service) and you risk phasing yourself out completely. The database is already out there and other sources are popping up. Included with my Garmin was direction to their Open Caching website which features user-submitted caches. This site looks to be innocent of database-robbing as it is devoid of most of the caches in my area that are listed on Groundspeak's site, however it's not that far of a leap for a less reputable third party to use the database and build it's own user-base where it would no longer need to sync with Groundspeak.
It's an honor-based hobby in the first place and no matter what your pleasure, there's always DB's that are going to taint it when left alone to do the right thing when nobody's looking. I'm quite sure that there's probably a paid member or two that are guilty of the same crimes mentioned in this thread, and it's not fair to say that ALL Intro users are bad and don't care, but what we can agree on is it's the people that make it bad and that's what needs fixed.
What about an official GC.com weather-proof rule/etiquette card affixed inside the cache to increase awareness? Sure it wouldn't fit in micros, but there's not enough room to pervert a micro in the first place. I think Groundspeak has done all they can to try and improve the sport with PMO caches and their wealth of information on their site including proper etiquette and so forth. Sure there's a disconnect between GC.com users and the rest, but they all come together at the cache itself, so the cache is where the information to fix the problem needs to be IMHO.
