My fear would be them just checking in fictitious kills, because how many western states require kills to be checked in person? If the kill data stays the same it would likely be a lot harder and take a lot longer to allocate more tags to offset the problem.
You could put some law in place saying tag holders have to attempt to hunt, but this would really only keep them from publicizing their true intentions. There are similar laws for waterfowl blinds in my home state, where a riparian land owner can keep others from hunting public water near his land so long as he builds a blind and "hunts" it at least once a year. This now amounts to a $20 donation to the state agency a year for the annual blind tag, but one blind effectively cuts off half mile of public water. Certain large areas of public water are now are completely unhuntable because of it.
