Misinformation, the unintentional spreading of false information, occurs frequently on social media such as Facebook and especially on WhatsApp.

Disinformation, the intentional spreading of false information, is even more sinister. An example of disinformation is the reported Russian interference in the 2016 U.S. election. In the 2020 U.S. election Facebook had a policy of allowing political advertisements that contained outright lies.

Advertising can also at times be viewed as being designed to deceive.
