Expose an OTC merchant, everyone be careful

A friend sold U at this OTC merchant, and within 5 minutes of receiving the money, their bank card was frozen. Then they received a call from the Nanjing Public Security Bureau saying that the money received was dirty money. The police demanded a deduction of over 400,000 before they would unfreeze it. Everyone should avoid this merchant, as it is not only dirty money but also first-hand dirty money. This is too dangerous.
