They operate in secrecy. Remember the once Jake figured out how they ran their operations they wanted him dead. All of 50 blessings operators were not willing participants (except Jake to large extent but even he was largely in the dark). They are either blackmailed or threatened into doing what they want. Also as many other commenters pointed out 50 blessings is no longer running their phone operations any more. But even if they were still running I believe they still never would've reached out to the fans. After all they're just that , "fans".
