Well - if we take a big leap here and assume that one of WakeMate's founders is a mod and this person deleted the post then the policy is not so good.

A possible approach is to allow the mods to have aliases to their usernames (and PG and company can be the only ones knowing the correspondence of alias to username). This way - HN users could see the history of deletions of a particular mod without knowing the actual user.

Granted, HN users are smart and someone could probably create a data mining app which would find the actual user by looking at pattern of deletions, topics of posts, etc... but that's life and that's what you get for having a lovely place such as HN.
