Thus, WhatsApp was fined 4 million rubles, Facebook - 15 million rubles, and Twitter - 17 million rubles for repeated violations of data localization requirements (part 9 of Art.13.11 of the Administrative Code).

Last year, Facebook and Twitter were already prosecuted and were fined 4 million rubles each.

Then Facebook paid the fine, but Twitter did not.

According to the law, companies must ensure "recording, systematization, accumulation, storage, clarification (update, change), extraction" of personal data of Russian citizens using databases located on its territory, Roskomnadzor reported.

The Magistrates' Court of the Tagansky District of Moscow on July 22 fined Twitter 5.5 million rubles for refusing to remove prohibited content.

On the same day, Facebook was fined another 6 million rubles for not removing prohibited content.

On August 24, Twitter and Facebook appealed against the fines.
