Did you read the Clarify Capital article? The definition of “ghost job” does not support the point you’re trying to make. The definition of “ghost job” in that article is so broad it includes pretty much every job post. A job post being open for 30 days does not make it a “ghost job” by any reasonable definition. The Congress publication includes no evidence or conclusion and even notes that the issue of ghost jobs is disputed. Did you just google ghost jobs and copy the first 2 links without reading them?

Even within this HN post there are people claiming that almost 100% of the whoishiring jobs are fake which is demonstrably untrue: https://news.ycombinator.com/item?id=49823091
