Why on earth would anybody ever want to adopt an archived cache? If it was that good one could put a cache with an identical description (even an identical puzzle) in the same place in one’s own name!
If the owner has lost interest in a cache it should be marked “needs archiving” so that the reviewer is alerted to the problem.
When a cache has been archived it is reasonable to treat it as geo-litter and remove it from the countryside. One could, if one felt that one had committed a criminal act, e-mail the owner to seek instructions for its disposal or return!
