If you don’t get any responses to the rebuttal, does that mean the scores will remain the same? I had a borderline paper (6-6-5-3 with conf 4-3-3-3) and the rebuttal questions were all easy to address (theory questions with well known answers) and I ran the experiments they wanted.

Rant: they should at least have a button to acknowledge they don’t need to send a message. For some of us applying for faculty or applying for PhD, admissions to these conferences make huge differences in our life. Such malaise is super stressful and really sucks for some of those who would have benefited greatly from an acceptance.
