A case of double bluff – this was the conclusion Swedish internet users reached after a Swedish website presenting itself as the next in a series of websites devoted to checking facts and challenging disinformation turned out to be doing the contrary of what it claimed – not checking but reinforcing disinformation. As we have reported, awareness of the disinformation problem is growing both globally, via e.g. the First Draft News project and self-help initiatives, and locally in many EU Member States, e.g. France, Denmark and Sweden, where e.g. theViralgranskaran project now counts more than 70,000 followers in Facebook.
