Let's not get carried away here. No-one is suggesting that even remotely thinking you'll go public with a PM would be anything other than an extremely rare event. Now I've done it just once (not here, I don't think) in ten years and y'all know what sweetness and light I am. ;-) As Jack implies, I think, there may be that rare occasion when you would be doing the rest of the list a favour in letting them know what a bloody eejit the offender is. But if you do it capriciously or over-frequently for no good reason, or if you're a known whinger or shit-stirrer yerself, of course you'll be seen as a dickhead. I'm racking me brain here and I can't think of a single example of a time when I've seen disclosure and regarded the discloser as anything other than a person driven to distraction by a knobhead hassling him with stupid PMs. Having said that, I've seen many an accidental disclosure resulting from someone hitting the wrong key. They are tons more frequent than the deliberate sort. To be honest, this is a bit of a storm in a teacup, innit.
