Abstract
For some time now, there has been a lively debate about false information circulating on the Internet. Especially in the context of information on COVID-19 and elections, their increasing spread can be observed. Even though established news media and content are often referred to as "fake news" by individual actors, the debate does not usually focus on traditional news providers. Rather, social media and online offerings that are more likely to be located on the political margins, so-called "alternative" media offerings, are suspected of disseminating false or misleading information.
