A very easy solution for these FTF hogs would be to eliminate the option of receiving an email notification that a new cache has been placed. Then there would be a bit more challenge in finding one.
Twice this year I happened to be visiting an area for two nights, loaded the map, clicked on a cache to get its coordinates, and saw that it had not been found yet (at the time I was a non-premium member, so no email notifications), and went out the next day and found it.
To me that was a lovely reward for being in the right place at the right time.
