Out - be my choice
Perhaps a quick examination of the realities of this fine site and the facts surronding its useage help us answer the original question:
It is a rumourr site.
The Moderators do from time to time step in and make comment, give guidance and on occasion take action. (As a fellow antipodean can atest! Where for art thou Ned?)
If it were not appropriate for us to choose to be anonymous and observe, comment or even rant from anonimity there would not be the function to allow us to do so on this site.
To the question of outing! Whether you are pilot, pretender, pedant or even an accountant (wink wink Whirls) it should be your choice when, and if, you choose to out yourself and to what degree.
To me it speaks volummes, and not necessarily good ones, about someone who threatens to, or actually does, out someone else participating in discussions on this fine site via a non de plume.
