These folks have been holding underwater photo competitions and promoting the underwater world since before most of us were in diapers. I don't think they really had any other choice did they? Do you want to be put in the position of somehow proving that the images you enter in any contest was shot "legally"? How are you going to do that?
Do you want your once in a lifetime image thrown out of a competition because you might have manipulated the subject? And the judges are afraid of what might happen if they award your photo?
Well Steve, the negative tones aside, it is precisely the dissent and questioning that caught out a few people who've cheated like that of "Wolfgate." In this case, assuming certain parameters, the probability of capturing that shot "wild" is very low. Reconstructing how a person gets a shot like that with a 60mm on a D700, the mating behavior and height which the seamoths, I think we can make a case to ask someone to prove how they took that shot and show proof.
The problem for LAUPS is they've already announced the results, so pulling back the prize on what cannot be an absolute certainty that the subject was manipulated, is very difficult. Admittedly the added difficulty of asking someone if they cheated is tough, as is expecting an honest answer if someone has done so, is even more implausible.
Furthermore, this isn't the first time LAUPS results have been questioned:

It's always easy to judge in hindsight but that's why organizations like BTS played heavy hand in this decision:

They decided the unnatural background was too much for a category winner, based on the comments by a few people. How did it get past the first cut and judges? It's because the knowledge isn't out there. So while the photographer can say they didn't know it's unnatural, doesn't mean it isn't unnatural and it wasn't put there for their benefit.
I do think there is no need to be rude about questioning LAUPS about their competition. State your opinion politely. If LAUPS' rules for competition and judging doesn't work for you, you are welcome NOT to enter their contests. That said, it'd be nice to know that competitions like LAUPS will become more vigilant in enforcing their own rules.
