As for the comment, If a mod reads something in a PM, is it acceptable for them to divulge that in a thread or in open forum?, no, it is not acceptable. Fortunately, the choice of Augustlan, who has the ability to keep mum about the atrocities that she may be called upon to view on this site has the gracious ability to keep the content restricted to the parties involved.
Even the moderators, who volunteer and receive no monetary reimbursement, appear to have the tact to keep comments about moderated public posts between themselves. For me, they all set an example of how I want to act both on Fluther and in the outside world.
