Some of the worst behavior I see is when an experienced geocacher logs a WJTB/YJTB as being found in a new cache and writes "took the Jeep TB as a First Finder's prize."
Dudes, they're not prizes. In fact, they're not trade items. I get frustrated when I have a cacher go to my sites and log something like:
T: Cool laser level and 4 AA batteries
L: BlahBlah TB
Since my wife and I have stocked our caches with cool stuff, I've started upgrading the level of difficulty to reduce the junk piles in them. That's the same rationale for my placing a Jeep TB in a really hard wilderness cache. I know it makes it almost impossible for less capable cachers to get one, but at least I moved it promptly, and the next finder will have to put some effort into obtaining the desired find/TB. I don't bother with placing them in multis- a lot of people who have solved the multi will just walk to the last stage and pull the jeep out at 2AM since they know where the last stage is.
I think to be fair, to enter the contest you should have found the Jeep TB in a cache that was a new find for you. Too many people just watch the local caches and go out at midnight to a previously known/found cache, without the need for GPS, and raid the container to get one. I guess that's okay if you plan to play the game and move it, but getting a Jeep TB in a new find was a real treat for me.
