I applaud you for you effort. Fatigue management should be exposed. As you well know putting folks in front of a camera does little to fix the problem other than bringing attention in that moment.
This is one area there area where there is no international standards. Each country decide what rules they will abide by. Each counrty determines how much oversight they will do less commission (payoff) to the principal operating inspector (POI).
All the above ideas are good . . . allow me to add, exposing the differences by country and I suppose company. Pilots can scan and email you the rules from their operating manual and/or country regulations. Alot of work, but you might be surprised at the vast differences. Then expose countries/companies with less restrictive rules.
