I have been the second "hider" on several caches that are owned by another. As such I am not the "owner", but I can't really "find" it either.
It is possible to "ignore" a cache. It is possible to exclude "ignored" caches from pocket query's . That is all good.
What is NEEDED is the ability to EXCLUDE "Ignored" caches (along with "found" or "hidden" caches) in "searches" and on "Geocaching.com Google Map" and whereever else.
