It is impossible to legislate behavior.
You can set all the rules that you wish, but if someone chooses to ignore them, well....they ignore them. Romeowood has made valiant efforts to instill a sense of ownership and responsibility in the Box Pass participants. Adding more rules, I'm afraid, will not alter the outcome. The only way to assure compliance with the Box Pass rules is to have recipients sign a contract and tender a deposit. That sort of negates the whole "Brotherhood of the 'Baccy" thing, though, don't you think?
Despite our professed high opinion for the pipe-smoking community as a whole, it turns out that we're no better than the general population. That's both disappointing and reassuring. Having to live up to the outlandish standard of honesty and relative decency is, after all, such an unreasonable burden to place on someone that you have bestowed your heartfelt generosity upon.
The only time that I've ever seen absolute honesty on the Internet is on a forum of Federal Firearms License holders, where reneging on a firearm transaction could result in felony charges. All of that predictably decent, dependable and conscientious behavior gets so tiresome after a while, though. It just doesn't seem normal.
So my hat's off to the 'Baccy Filchers everywhere for keeping us human.
