Digital scam data is invisible. So we made it visible through data visualization. Whoscall, an app that protects users by blocking scammers before they can make contact, aimed to help Thai seniors understand the magnitude of the threat. So we took something they trust, the Yellow Pages, and recreated it using our entire database of scammers in Thailand: “Whoscall Scammer Pages: Scam Edition.” A 1,500-page printed phonebook made entirely from Whoscall’s real database of over 1.5 million scam numbers. With real scam numbers and real cases, bound into a book five times thicker than the original Yellow Pages. This book turns an abstract digital problem into something real, physical, and impossible to ignore. The Scammer Pages became a national agenda to raise awareness of the impossible-to-avoid threat for Thais.
