So far I don't really enjoy solutions involving mods. It just takes up too much time from their already busy schedules and things to do, which can be used for better things for the forum, than to monitor these quibbles between normal people.
catchlights brought up a good point - "...that is a "culture", "custom" or "ritual" for them to fly photographers aeroplane..."
It's not going to be easy and it will take a lot of collective effort from these photographers to implement, not to mention, there will always be new blood from both photographers and models (with short shelf life) and the same problem will keep repeating itself, unless the culture or custom can be changed.
I agree with you that it should not take up too much effort from the mods.. I'm not sure how serious or frequent the problem will be. Seems that it's only once in a blue moon kinda thing to delist (which requires mod's attention)?
The 2nd part is valid too.. But if there are members like TS who is willing to contribute (judging from the comments).. the source of effort from photographers might not be an issue..
