Advertising is not free. Having a few unfilled jobs is natural but it's wasteful to have significant market disconnects.

That said, a lot of 'jobs' are simply H1B fodder or resume bait etc.

Unless they people causing them waste incur costs greater then they benefits, it won't change. Hiring has gone digital, reducing costs, so of course garbage job postings have increased.
