I think it would be super helpful to be able to set administrators for different regions which can manage all the crazy segments being made.
For mountain biking, there's an app called TrailForks, and thats how they manage new trail creation and keeping trails up to date. The administrator can remove routes and make sure everything is kept accurate, safe, and fair.
Could you look into making a system for having regional administrators?
Maybe something like the top 10 riders who ride the region's trails in that sport are asked if they would like to be an admin, and that you have to remain active in your admin duties to keep it. Able to send messages to and from the admin and anyone who is making crazy segments. etc.
Lots of possibilities here.
