Is it really fake to forcibly set Lao Lai's ringtone?

This CRBT service is mainly launched by some local courts and communication operators, aiming at those who are recognized by the courts as untrustworthy executors. The purpose of setting up this color ring back tone is to increase the exposure and punishment of faithless people and urge them to fulfill their legal obligations as soon as possible. The specific implementation may vary from region to region and operator, and it generally needs negotiation and cooperation between the court and operator.
