Competing Interests

The authors have the following interests: Wong Sak Hoi is employed by swissinfo.ch. The relationship between the University of Warwick and swissinfo.ch exists solely within the context of the PHEME FP7 research project, funded by the European Commission, and this collaborative work has been performed entirely within, and funded by, this project. There are no patents, products in development or marketed products to declare. Swissinfo.ch, as part of its parent organisation SRG SSR (the Swiss Broadcasting Corporation), is a non-profit entity, and the role of Wong Sak Hoi in this publication has been strictly to provide the journalism perspective and expertise on the subject of social media rumours and verification. This does not alter the authors’ adherence to all the PLOS ONE policies on sharing data and materials, as detailed online in the guide for authors.
