This has been debated in the past, but keep in mind there are some very clever people in our Community that would be able to "Battleship" hidden waypoints under such a scheme. Even if you limit the number of coordinate changes to frustrate this sort of behavior, I've heard that it can be done with as few a number of guesses as two.
If you're submitting a Listing in an urban area, I highly recommend that you request coordinate checks prior to placing a cache, in order to lower the frustration and the amount of walking or driving you need to do comply with the Saturation portion of the Guidelines. Link for reference:
Checking for Geocache Saturation
I did do the saturation check first and we did find the cache that was said to be in conflict to ours and all is well within the criteria for placing a cache in the location we desire (Further than 161m).
This listing is out of suburban area and it has some significants to us. (Hence the reason for placement)
Any way I will just wait and see how the submitted location comes back from reviewer once again and see what happens.
