A fairly common source of misleading information is fake social media accounts or fake websites. Fake social media accounts are different from bots, which are created electronically. However, fake profiles on platforms like Facebook or Twitter tend to be carefully crafted handled aimed at mimicking someone else and putting out content deliberately intended to mislead readers/viewers.
Fake news websites are also not to be confused with satirical websites. The former also consciously put out fake news, often sourced from elsewhere, whereas satirical news sites typically put out stories that are fake but are intended to make fun of someone or something, with no ulterior motive of provoking trouble. Unfortunately, mainstream media, and even social media, often falls for such sites and there have been examples when satirical stories have been taken at face value and represented as real news.
