Second, feedback from players. Then, steps are taken to limit or restrict, or even ban thise things from the games. Limitations, restrictions, and bans are not taken lightly, and are not instituted based on whim or caprice. There is a good reason for them, at least in the mind of the game producer, and there is no doubt in my mind, that the game producer will be more than happy to answer questions about the limitations, restrictions, and bans he imposes. Trying to get them answered while the game is running and the prduction staff is up to its collective eyeballs in alligators, is going to be like pulling teeth, and the explanations they give at that time, will be insufficient to satisfy some players, and the constraints of time will not allow for a full and detailed explanation.
All game producers have restrictions, limitations, and bans.
Just read any of their information sheets and registration forms that are sent out prior to the game. They are there for one of two reasons - the safety of the players, or the enjoyment of the game by the greatest number of people. Others have taken his basic premise to other areas of the country, and by doing so, have introduced large numbers of players to the scenario game, thereby growing the sport, and benefiting the industry as a whole. The industry, in turn, provides greater support for scenario games through more prizes donated. I am a firm beliver in the wisdom of the ages.
