Prevent job board scraping (Glassdoor)

Summary

How can I prevent Glassdoor to scrape jobs from our internal career section?

Hello there,

We have recently found out that Glassdoor was scraping jobs from our internal career section. I do not think this is happening with other boards such as Indeed. How can I prevent this from happening?

Setting the career section as private is not making a difference, and so far we have not been willing to restrict the access to the career section via IP addresses, so that employees can access the jobs from a home pc.

Anyone knows how I can avoid this?
