No evidence given to support this allegation.

Ukraine blocked access to Vkontakte and other Russian social media for security reasons, as part of a broader set of measures by the National Security Council (NSDC) to expand “personal economic and other restrictive measures (sanctions)” against personalities linked to the Crimean annexation, terrorist activities, illegal border crossing, and 468 Russia-based or Russia-affiliated companies.

According to the Secretary of the National Security Council (NSDC) Olexandr Turchynov, such measures were taken as Russian Internet resources “threaten information and cyber security of Ukraine” and “are used for propaganda and the recruitment of agents by Russian security services.”
