TASS said the Russian interior ministry had opened a criminal investigation against Stone but that the ministry had not disclosed the details of the investigation or charges.

Meta’s main social platforms – Facebook and Instagram – were both banned in Russia shortly after Moscow’s invasion of Ukraine in February last year.

In March 2022 the Russian investigative committee said it has opened criminal investigation against the “illegal actions of Meta’s employees” and mentioned Stone, saying he had “lifted a ban on calls for violence against the Russian military on its platforms” and was thus inciting extremist activity.

Meta’s press office did not immediately respond to a Reuters request seeking comment from Stone and Meta out of normal business hours.
