Nope. The more I have considered this thread the more I am convinced this is not harmless amusement.
It was evident the meaning behind this was to embarrass a fellow GN and make mischief between he/she and others who connected with the obvious post this thread eludes to.
This has also made a mockery of the pm facility if it is considered OK to quote verbatim something which was meant to be private, irrespective of whether that pm was of a personal nature or not, or indeed sent in error. Has this ever happened before, I am not aware of it in the 3 years I have been on GN.
I had a pm that was not particularly pleasant but I chose to ignore that person, I could have done the same as this and quoted her words but that would only be my getting revenge and creating issue after issue, as this has done.
If causing embarrassment wasn't the purpose then all it would have taken is a return pm to the sender saying it wasn't appreciated, bringing it to the attention of others has however served it's purpose hasn't it.
