I would have thought knowing who was proposing the presentation was a significant factor in its evaluation as that provides the critical point of whether the person has the knowledge  to speak about the issue. Such games make the process appear to be unprofessional offering very little in the way of addressing critical issues and potentially opening up the community to abuse.  

Annon review is fine as that enables the reviewers to be critical without a concern of some backlash, I hope that before you publish the reviews publicly  that you consider the impact of those reviews, what is actually and ensure the reviews dont do harm to the person receiving them
