Complication
"Mumsnet apologises to Gina Ford for the comments made about her by some mumsnet users, and has made a contribution to Gina Ford's legal costs."
I wonder if it would be possible to extort from a site by posting negative comments throughout its forums, and then taking it to court for defamation. I do not suggest this is the case here - I believe the commenters at Mumsnet were well-know to the site's operators - but it makes me wonder how the owners of a site with anonymous or pseudonymous commentators can sleep at night.
Then again, a named and identified commentator could be nobbled, so I suppose there is no defence against this sort of hypothetical con game.
