Let's talk about: LinkedIn ghost jobs

LinkedIn has an obvious problem with ghost job postings. A good example: received an email of matched jobs. Opened it and followed one specific link only to see they were no longer accepting applications: https://www.linkedin.com/jobs/view/4439726696/ The job was reposted 7 hours prior and only received 36 applications total. I always assumed that ‘not accepting more applications’ meant a specific threshold was met. But 36 apps in 7 hours? No. Thoughts on what’s going on here?
