> When 99.9% of posted jobs are fake (including in HN's Who's Hiring)

Okay there a lot of fake jobs, maybe not as high as 99.9%, though.

But what's the basis for saying that "Who's Hiring?" is fake? Why would a business seek out a relatively lower traffic job venue, field the traffic of submissions, and then ghost everyone who applies (or whatever is done by 99.9% fake jobs)? Why wouldn't employers just save themselves the effort and do nothing?
