Bird's Nest agent fraud alarm is an effective reporting behavior, which can provide relevant information to law enforcement departments and seek legal protection. But its specific effectiveness depends on many factors, including the specific laws and regulations involved, the sufficiency of relevant evidence and the efficiency of law enforcement agencies.

In China, the related laws and regulations strictly stipulate the fraud of Bird's Nest agents, such as the Criminal Law of People's Republic of China (PRC). If the agent fraud of Bird's Nest involves criminal acts, such as fraud or false advertising, the police can initiate criminal responsibility investigation procedures to safeguard fairness and justice. If the bird's nest agency fraud involves illegal acts, such as violating the Commodity Quality Law and the Consumer Protection Law, the alarm can prompt relevant departments to investigate and provide legal protection.

But the effect of alarm depends not only on the alarm itself, but also on the active cooperation and work efficiency of law enforcement departments. If law enforcement departments take reports seriously and have the ability to take corresponding actions, the role of alarm will be more obvious. On the contrary, if law enforcement departments have limited resources or low processing efficiency, the effect of alarm may not be ideal.

To sum up, although alarm is an effective way of reporting, its effect is affected by many factors. In order to solve the problem better, it is suggested to collect enough evidence before calling the police and actively cooperate with the investigation work of law enforcement departments.
