NeurIPS reviewers not engaging [D]

So I know this is an ongoing issue at ML conferences, reviewers just tend to ghost. Do people have any strategies or recommendations on how to nudge them to engage with the rebuttals? Is it recommended to post a comment saying something like hey we want to engage with you? This might be a hot take, but maybe NeurIPS should penalize the reviewers' papers if they don't engage (I believe this year they withheld scores for ACs who didn't post meta reviews on time if they had papers submitted).
