How does who report a fraudulent online music distribution agency and directly contact the platforms for direct revenue?

I assume you are a registered member of ASCAP or BMI, also known as "PROS". PROs are responsible for collecting income on behalf of songwriters and music publishers when a song is publicly broadcast. That means PROs track down cash for you when your music is played on television and AM/FM airwaves, through internet radio services like Pandora, at a club, inside a restaurant, at a concert, or publicly broadcast in some other fashion. These places and stations pay fees to PROs, who in turn pay their registered songwriters- if you suspect fraudulent activity, immediately report it to whatever PRO you belong to. While the system is far from perfect, it is your only logical and least expensive choice at THIS time; there is active legislation to reform licensing rights and protect songwriters and musicians and the payments available through various licenses so keep yourself informed.
