Just a personal opinion, but as an occasional job seeker here, I prefer the current system, seeing "no complaints in replies" policy as efficiency, not censorship. Were it not the case I suspect many job postings would become discussion battlegrounds and people looking for brief summaries would have to scroll through pages of discussions.

It is a painful process for both the seekers (who feel they are being ghosted) and the employers (who feel they are being spammed by AI bots); IMO the best approach is to follow the general HN guidance of "be kind" and "assume good intentions". And if a company ghosted you, downvote their post. My 2c.
