This document discusses how charities can leverage social media to promote their causes. It provides an example of how Mind, a UK mental health charity, used Twitter to generate publicity and donations in response to offensive Halloween costumes. Through sharing personal stories, celebrity endorsements, and coordinating media volunteers, Mind was able to turn negative social media attention into over 1,600 articles of positive coverage and a £25,000 donation from the retailer involved. The document advocates that charities amplify supporter voices rather than act as a mouthpiece, in order to build collective strength and support for their mission.
