The proposal I think is simply to force listings to have more details like hire and start date, if it's for a backfill, if it gives priority to internal hires, etc. So the enforcement I think would be if you post listings without those details, you get fined. How you'd prove if people added false details I don't know, but I think the idea is at least by giving more info on the listing it might deter some ghost listings or enable the applicant to determine if the listing seems legit.
