the website, Mumsnet also hosts sponsored discussion threads that act as product placements. These sponsored threads take the form of sponsored Q&A threads relevant to the products being marketed, or of "product tests", where site users are offered free samples in exchange for feedback. In 2010, the Advertising Standards Authority extended its Code of Advertising Practice to include a requirement that paid-for promotional content on social media should be clearly identifiable as an advertisement. In response to this, Mumsnet began to mark product placement discussion threads as "sponsored threads"; during the website's first 10 years, no systematic distinction existed for users to discern between paid-for discussions and user-generated discussions. Webchats The site has hosted webchats with celebrities and politicians. Then-Prime Minister David Cameron was challenged over the provision of free nappies for disabled children, and in 2011, UKIP leader Nigel Farage told Mumsnet users that UKIP MEP Godfrey Bloom was "100% right" in stating that "no self-respecting small businessman with a brain in the right place would ever employ a lady of child-bearing age." In 2019, Jeremy Corbyn and John McDonnell have both faced questions about the Labour Party's Brexit policy and inter-party issues of anti-semitism. Jamie Oliver, Dawn French, Gok Wan and Clare Balding have all also taken part in Mumsnet webchats. Hillary Clinton also did a video Q&A in 2014. Mumsnet books Mumsnet has published several parenting books, based largely on the advice posted by the site's users since its launch in June 2000. These are Pregnancy: The Mumsnet Guide (2009), Toddlers: The Mumsnet Guide (2009) and Babies: The Mumsnet Guide (2010). The website's latest parenting guide, The Mumsnet Rules, was published in 2011. Other publications include a cookbook titled Top Bananas!: The Best Ever Family Recipes from Mumsnet (2014), The Book of Bedtime Stories (2013) and How to Blitz Nits and Other Nasties (2017). Lawsuit In April 2006, lawyers acting for "childcare guru" and former maternity nurse Gina Ford contacted Mumsnet in response to bulletin discussions of Ford's parenting methods, in which users had advocated for personal attacks to be made on Ford and her family. Ford's lawyers claimed that these threads constituted libel, and requested immediate removal of the posts in question. After 12 months of discussion, Mumsnet settled the dispute by apologising publicly to Ford and making a contribution to her legal costs. In November 2010, Mumsnet co-founder Justine Roberts wrote to Prime Minister David
