Mystery- or multi-caches are not published with their real coordinates, but with fake coordinates that have to be within a certain distance of the cache. Reviewers however need to receive the real coordinates of the final cache (or all stations) to ensure that they are according to the guidelines.
Apparently some reviewers leak this information to fellow cachers, which is against the idea of mystery and multi caches.
I heard the story of a person who created mystery caches and send wrong final coordinates to the reviewer, people who solved the mystery were able to find the cache, but some people complained that the cache was nonexistent. After being questioned for the coordinates they were searching at, they posted the wrong coordinates that were given to the reviewer.
The person who left these reviewer-traps was reportedly met with hostility afterwards.
How should I correctly handle this problem if I ever encounter a reviewer who leaks coordinates?
Disclaimer: I am new to caching and have not encountered this problem myself, but heard about it in a podcast.
