On one of the manuscripts I am editing, the reviewer initially agreed to publish her name, and now is requesting upon revision that her name be removed.

Needless to say that this puts us in a tricky situation. 

I would therefore propose that either we clearly state that identity if revealed on the first set of reviewer comments, cannot be hidden anymore.

Or, maybe more cautiously, that we shield identity until the article is published (which is common in many journals). Because often discontent arises during the revision process. 

Your thoughts please,

Thank you
