Possible situation:

Hunter asks the farmer he hunts on if he has seen any big bucks. Farmer says yes and tells hunter where and when the big buck usually feeds. Hunter sets up and using information provided by farmer, kills the big buck the very next day. Are you going to exclude that big buck from being entered into the contest? Sounds as sensible as banning a member from being on a team simply because he uses an outfitter for one week.
