What is the reason why the company address is not written in the recruitment information on the recruitment network?

This problem is too simple, because the recruitment website charges the enterprise by publishing the recruitment information service, and the address does not flow. Officials want visitors to get in touch with the company by registering the company's website (some even charge a fee), which is also an accounting method for the website to charge the service fee to the enterprise.
