Netizen's phone service suspended by anti-fraud system after call with friend, accused of discussing sensitive words

Recently a netizen posted that after a phone call with a friend they received a service suspension notice, and the anti-fraud center also called their friend to warn them to be careful with that number. Staff said they may have discussed sensitive words, and that the number had been flagged as impersonating a police officer; after applying to have it lifted, service was still not restored.
