Russia’s communications regulator Roskomnadzor added LinkedIn which boasts to be the world’s largest business network on the blacklist and notfied internet providers about blocking.

In August, Moscow’s Tagansky District Court granted a motion filed by Roskomnadzor seeking to block access to LinkedIn in Russia. The Moscow City Court upheld the ruling on November 10.

Roskomnadzor claimed that the social network violated the law on personal data storage.

LinkedIn said that Roskomnadzor had lodged the claim unreasonably. If personal data owners consider that their rights have been violated, they are to turn to court and apply to Roskomnadzor. In this case, the regulator has turned to court advocating for indefinite range of persons, the company’s representative said in court.

LinkedIn is the world’s largest professional network with more than 450 million members in over 200 countries and territories, according to its website.
