Thanks for the update Justine. I did email MNHQ (not that I've received a reply, harumph) the other day with my thoughts on the media fall-out, particularly Riven's privacy being breached.
Here's (some of) what I said...
I saw the start of Riven's thread yesterday just as the first cries of "contact the media" were going up. I could tell straight away that this was going to be a huge story.
Then there was a massive - and, of course, massively well-intentioned - rush to do something, anything to help. And before anyone knew it, people were contacting media, tweeting journalists, setting up Facebook accounts etc etc.
What should have happened, as this rush to action was happening, was that someone should have taken a minute to say to Riven, "Look, this is going to be a big news story. The media are going to want to speak to you; they'll use the pictures of your dd that are on your MN profile and have already appeared in the Telegraph; you will have people camping on your doorstep wanting to speak to you. If you don't want that to happen, you should say something now". In hindsight, I wish I had posted it, because Riven seems genuinely shaken by what's happened and I'm sure would never have wished for all this attention, whatever the ultimate outcome of her story is.
This is not a criticism of anyone at MNHQ, by the way. There are many media-savvy MNers who could have sounded a note of caution and I am sure that you were advising her as best you could.
What we all - as a community - need to learn is this. The Mumsnet brand and community is more powerful than ever. People DO take notice of what happens on there and that is multiplied when MNers actually go out of their way to bring it to the media's attention. And once the genie is out of the bottle, you cannot put it back: the story will develop a life of its own and the media will not stop until it gets the story that fits its own agenda or the day's news cycle. This can be to the greater good, of course, but good people can also be damaged in the process.
I'm also not sure how it can be combatted - this isn't a simple case of putting some guidelines at the top of the AIBU board. I guess what I'm saying is: you have a very motivated group of people acting on behalf of the MN community. When these ad hoc campaigns pop up like this, perhaps some of us (at MNHQ and posting on the threads) just need to be the voices of reason from time to time. Beyond that, I'm not sure what other concrete measures can be taken.
Sorry, I know you're all talking about the bigger issues now, but I wanted to get that off my chest.
