"Social networks allow ‘atoms’ of propaganda to be directly targeted at users who are more likely to accept and share a particular message.
Once they inadvertently share a misleading or fabricated article, image, video or meme, the next person who sees it in their social feed probably trusts the original poster, and goes on to share it themselves.
These ‘atoms’ then rocket through the information ecosystem at high speed powered by trusted peer-to-peer networks. This is far more worrying than fake news sites..."

Almost all news outlets (legitimate and fake) rely on advertising as a source of income. Professional journalists and editorial staff are paid to do quality work, including fact-checking, conducting meaningful and ethical interviews, and striving for objectivity. They work quickly, but it still takes time, effort, and money. When readers are drawn to "news" not to learn information but to confirm pre-existing beliefs or to feel the sensation of being outraged, fake news sites draw traffic from legitimate sites.
