No Fly Zone allows people to contact them and a section off restricted airspace, but they need to provide proof of residence such as a lease agreement or a utility bill.
The ability to rescind blockages is especially important because No Fly Zone allows anyone to add any address to the list with no formal verification process. I didn't have to show any proof of residency to register my parents' house in the San Francisco Bay Area.
The site's Terms of Service explains that not all drone operators and manufacturers will necessarily agree to opt into the program because doing so is entirely voluntary. It also isn't guaranteed that all of the ones that do participate will load their machines with the most recent version of the database.
