Claiming to be "public opinion supervision," in reality it is extortion and blackmail. Self-media critics have become a malignant tumor on businesses.

In recent years, a group of self-media accounts under the guise of "public opinion supervision" have been fabricating and exaggerating negative information about companies, and then extorting them under the pretext of "business cooperation". The abnormal ecology where the cost of enterprise rights protection is high and the cost of illegal rumors is low is becoming a new type of cancer in the business environment. Not long ago, a rapidly growing coffee company in Shanghai was deeply involved in this, and under the carefully woven rumor trap and relentless pressure from the self-media blogger Su, this company reluctantly paid a "hush money" of 225,000 yuan.
