Consider this freepmail.

Perhaps I can speak to this. I received some truly foul and abusive freepmails some time ago, and my preferred response at the time was simply to post the freepmails in public, allowing folks to see what sort of person this poster actually was when he/she thought nobody else was looking. But before I did, I popped off a freepmail of my own to the admin moderator, asking about the appropriateness of posting private mails in public - the response I got was that while there was an informal, unwritten rule about that sort of thing, violations were considered essentially bad form, rather than as serious offenses deserving some sort of official sanction. However, in a case like the one I described, the moderator was doubtful that anyone would find my posting of the mails to be inappropriate, and that I should therefore let my own conscience guide me as to whether or not these private mails should be posted in public.
Consider this freepmail.
