Stand for the truth and against disinformation

Our goal is to limit the spread of disinformation across the internet. We alert advertisers that their advertisements may appear in a negative context and thus jeopardise the reputation of the advertised brand itself. Therefore, we ask advertisers not to fund misinformation and manipulative websites whose content divides society.

About us?

Methodology for identifying disinformation

We decided to use three different mechanisms and different approaches to determine harmfulness of a given medium while ranking the websites on our list.
Semantic Visions
Foundation for Independent Journalism (NFNŽ)
Konšpirá (Conspirators)

With a specialized military intelligence system OSINT, Semantic Visions provides advanced semantic analysis of big data. This is used to link billions of online news articles in 12 world languages (from over 900,000 publicly available online news sources).

Semantic Visions then turns this cluster of information into a unique knowledge base built on higher-level meanings (thousands of so-called semantic categories) that supports the identification of online trends, narratives and threats.

The company monitors 90% of online news content from around the world, which is analyzed and updated every 30 minutes. That's more than 1 million online news articles and blogs a day.

The Foundation focuses on three characteristics that are considered essential in assessing the credibility of a website: transparency of the medium, fair handling of sources and professional work with the content itself. This methodology assesses how sources and text are handled rather than the level of misinformation. It is a part of the overall picture as the majority of disinformation is based on poor, unprofessional work by the editorial staff which allows such disinformation to spread.

The credibility of a given website is examined by a committee (writer / political scientist / publicist / artist / doctor / biologist / teacher / historian...) based on their belief in the social usefulness of the medium. We have created an intersection of the sites that overlap in each analysis using these 3 different mechanisms and are, in our opinion, the most toxic and recommended for blocking as part of an ad buy.

*website traffic data - monthly average in 2019 (< 5000*) (2 012 000*) (237 008*) (872 156*) (638 333*) (7 040 000*) (566 373*) (130 761*) (529 944*) (632 356*) (1 047 000*)
Why consider Parlamentní listy a source of disinformation:
Willingness to publish obvious nonsense, manipulative and tendentious
Bending social issues through demonstrably disinformative narratives
Selling of support for politicians acting in symbiosis with the disinformation scene

How not to advertise on a disinformation

Together with our supporters, we have prepared a guide on how advertisers can block their ads from appearing on a disinformation website.


We are part of the international anti-disinformation platform and the partner of The Global Disinformation Index.

GDI aims to disrupt, defund and down-rank disinformation sites. We collectively work with governments, business and civil society. We operate on three core principles of neutrality, independence and transparency.

I want to support

We think there are several reasons for you to consider financially supporting our association. We work for the association for free and thanks to our professional backgrounds we are able to cover most of the work related to the communication of the association by ourselves. However, there are many things that we can't do ourselves or can't get for free and therefore we need money for:

  • buying online & offline media space for our campaigns
  • funding the technical background of the association - administration of the website, emails and newsletters
  • legal assistance in consultations and litigation
  • project assistance in larger campaigns
