ou might think that spreading fabricated news stories, false rumors and absurd hoaxes would become increasingly difficult as the web matures, with our ability to sniff out falsehoods growing stronger over time. Well, you would be very, very wrong.

With sophisticated digital image and video manipulation software, trigger happy Facebook sharers and lazy clickbait journalism practices, spreading lies is easier than ever before! News sites are all too eager to forego fact checking these days, citing shady blogs and unverified sources for quick-and-easy pageviews. Most Facebook users can't be bothered to do a quick Snopes search before posting the latest sensational story to their news feeds.

Some liars were exposed this year as well, including Rachel Dolezal, the former president of the Spokane, Washington chapter of the NAACP, who had a rather spectacular fall from grace when it was discovered that she was a white woman masquerading as an African American.

Additionally, Taiwanese model Heidi Yeh came forward in October, revealing that a hoax depicting her as a woman with plastic surgery who mothered several ugly children had a detrimental effect on her career.
