Supposing that a Bryce artist, tired of hearing how good a competing software was on another gallery decided to post an image done in Bryce on the competing gallery just to see how long it would take those erudite persons to recognize it for a ringer. Suppose that none of those on the other gallery picked up on it and instead found it just wonderful, gave it a great rating and favorited it.  What would you do? Remember this is all hypothetical, wink!
