It looks like that job posting gets repeated monthly, so the company name is building bad reputation, the poster can get blocked and if eventually they do need to hire someone it will likely bite them.

It might not put many potential employees off, but it might well put investors off if they get the idea that the company has shockingly bad practices when they look into their brand.
