Should more be done to tackle 'ghost jobs', vacancies that don't exist?

A BBC News article discusses the issue of 'ghost jobs,' where companies advertise vacancies that don't exist or have already been filled. Studies show that up to 34% of advertised jobs in the UK are ghost jobs. The problem is prompting efforts to tackle it, with Ontario in Canada requiring companies to disclose if an advertised vacancy is actively being filled. Experts suggest reasons for ghost jobs include creating a talent pool, inflating numbers, or obtaining and selling data. This practice can skew data and negatively impact job seekers.
