Employers don't post anything, the job listings are scraped directly from company websites. So even if the employer has not paid for an ad on Indeed/LinkedIn/Glassdoor but they leave the listing up on their company website then the scraper will pick it up (which is a large amount of listings). But yea asking the user to pay for the service is certainly different but I think beneficial because now they are the customer (rather than the employer)
