  The internet promised to democratize access to knowledge and make the world
more open and understanding. The reality of today's internet, however, is far
from this ideal. Misinformation, lies, and conspiracies dominate many social
media platforms. This toxic online world has had real-world implications
ranging from genocide to, election interference, and threats to global public
health. A frustrated public and impatient government regulators are calling for
a more vigorous response to mis- and disinformation campaigns designed to sow
civil unrest and inspire violence against individuals, societies, and
democracies. We describe a large-scale, domain-level analysis that reveals
seemingly coordinated efforts between multiple domains to spread and amplify
misinformation. We also describe how the hyperlinks shared by certain Twitter
users can be used to surface problematic domains. These analyses can be used by
search engines and social media recommendation algorithms to systematically
discover and demote misinformation peddlers.
