So my problem is every time I place a geocache I get a notice from a reviewer that there is a final of a mystery or a Wherigo or something else. Im just curious but bothers this problem only me or is this a well known phenomenon? Is there a possibility to know if the chosen location is free to place a cache or do I have to complete all caches around a possible hiding spot (I dont have the time to do this)? For me personally, I don´t do any mysterys or wherigos or other stuff only traditionals and multi-caches because of this problem.
