You can tell by searching your resume when you are working for talents. Resumes frozen by users are usually not searchable. At that time, my project was short of people, so I asked technology to find out all these things that I can't see at ordinary times by some means. At that time, many people answered the phone and asked, "Why can you still find my resume because it has been frozen?" This freeze is aimed at the human resources of the employer. They can't find it, but it can still be seen by recruiters in Cai Ying. At that time, the customer explicitly asked us to help them find it, so we called the job seeker directly to recommend the position of the customer.
5 1 should have a similar function. So if your situation meets the needs of some similar customers, it may be found out by the staff of 5 1, even if it is frozen.
In short, there is no absolute privacy in what is put on the Internet.
