Definition

Fake news websites deliberately publish hoaxes and disinformation to drive web traffic inflamed by social media.[3][4][5] These sites are distinguished from news satire (which is humorous) as they mislead and sometimes profit from readers' gullibility.[4] While most fake news sites are portrayed to be spinoffs of other news sites, some of these websites are examples of website spoofing, structured to make visitors believe they are visiting trusted sources like ABC News or MSNBC.[6] The New York Times pointed out that within a strict definition, "fake news" on the Internet referred to a fictitious article which was fabricated with the deliberate motivation to defraud readers, generally with the goal of profiting through clickbait.[7] PolitiFact described fake news as fabricated content designed to fool readers and subsequently made viral through the Internet to crowds that increase its dissemination.[8]
