In the US a lot of these are pseudo postings for immigration applications. They are technically posting the job, but in pt 3 for on page 72 of a random newspaper in a hope that nobody sees it and applies so they can say “we couldn’t find anyone so we need a visa/green card.”
That’s starting to get cracked down on, but it’s been a mess and a sham for a while.
In the US, there are a ton of them on major online job boards, not just some random newspaper.

That one is theoretically easy. When you apply, the job you “couldn’t fill” gets auto-posted to a very, very public government-hosted job board (with applicant tracking).
