In fact, any system provides only the possibility of anonymity. If the client himself is wrong or behaving incorrectly, deannonization is possible.
For example? Can you give examples?
For example, a client for a meeting with a girl takes his personal documents and mistakenly leaves them with her.
But we must also take into account that not every girl is capable of blackmail. Deannonization can take place without loss on both sides.
