> Most networks like Flight Aware allow owners to blacklist aircraft such that their tracks do not appear on the site.

Do you know more about how this is done? Is there a fixed price list for this service? Can one "buy" it online? Is there some sort of registry that is shared between networks?

> Additionally military aircraft are typically not reported.

While I'm sure the military can turn off transponders at will, I presume (?) they often fly with them on. Can these signals be tracked with "standard" gear when they are on?

The FAA runs the blocking programs, there's no fee https://www.fly.faa.gov/ASDI/asdi.html https://ladd.faa.gov/

A copy of the ASDI block list is on https://www.muckrock.com/foi/united-states-of-america-10/faa...

The FAA also has a new program to hand out pseudonymous aircraft identifiers via commercial providers so there probably is a fee for that https://www.faa.gov/nextgen/equipadsb/privacy/

FlightAware sells blocking services and dashboards. Don't be fooled, the privacy lobbying is only to make more money for FlightAware and FlightRada24.

Feeders sending them free data for fake enterprise dashboards and fake "$89 value" accounts have made David Baker a multi-millionaire.

I've heard that the first few years of flightaware they made most of their money in taking requests for not publishing specific aircraft.

As for military stuff - they have additional capabilities for their transponders that provide for responding to interrogators (think identify friend or foe - IFF systems). They're not supposed to disable transponders in the required airspace - they've got to comply with the FAA rules too. There are situations where ATC transfers control over to the military where they are free to do more things. Like in a hot military operating area (MOA) or when ATC transfers traffic separation to the military (MARSA).
