In 2015, during the refugee crisis with large numbers of immigrants entering the country unregulated, a broad discussion about the problems of mass immigration and politics of the actual government took place in social media. In this situation a campaign was started to force Facebook to erase right wing hate speech. Early in 2016, a Bertelsmann company called "Arvato" was mandated to erase comments and contents from Facebook.[18] Rules and procedure for that censorship, as well as the juridical base is not clear at the moment (January 2016).
