It would likely go against the spirit of the community to hound a job posting like that. I don't disagree with the sentiment, but turning the hiring posts into any sort of flamewar/off-topic discussion dilutes the value of those threads.
A (different) jobs board where the companies posting the jobs do not have control of the comment discussion would be interesting to see - but would need a monetization strategy that ensures it can survive without turning into pay-to-censor junky platforms like Yelp or Glassdoor.
