@Walter Hinteler,
More and more social media no longer give the
Identitarian movement a stage. This separates them from their base and considerably limits their radius of action
Martin Sellner is the head of the Identitarian Movement Austria, an organisation described by the Austrian intelligence services as "agents of modern right-wing extremism." The movement has been given the same label in Germany by its intelligence services.
Now, his YouTube account has been 'terminated', he also had his Twitter account suspended last week.
The extent to which right-wing extremists are affected by the banning of Twitter and other platforms is shown in the study "Online Ecosystem of Right-Wing Extremist Actors" by the German Robert Bosch Foundation. It shows that "blocking the accounts of right-wing extremist groups and influencers is effective in considerably limiting their reach". Especially since large parts of the following do not follow them onto new platforms.
In their analysis, the researchers see the content disseminated as "dangerous inspiration". "The posts focus disproportionately often on the negative consequences of immigration. As we have learnt from the manifestos of right-wing extremist assassins, right-wing extremist ideas such as the conspiracy theory of the 'Great Exchange' can inspire extremist violence and terrorism without actively calling for violence," says extremism researcher Julia Ebner of ISD, an independent research institute based in London.
