The FCC should publish all phone numbers that receive "too many" reports for violating the do-not-call list and other prohibited calls or calling techniques.
This list can empower applications developers and telecommunications carriers to build options for consumers to pro-actively block the offending callers.
How many is "too many" - how about 50 to start?
