Roskomnadzor demanded to unblock the Twitter account "Committee for the Protection of National Interests" (@inagent_net), which, as stated in its profile, "informs people about the activities of foreign agents on the territory of the Russian Federation."
“The blocked materials are independent investigations into the facts of foreign financing of the political activities of organizations in Russia,” Roskomnadzor claims.
It is not clear from the message what the agency means by blocked materials, perhaps this is how the RKN calls tweets.
The requirement to unblock the Committee for the Protection of National Interests Roskomnadzor "sent to Twitter": "The directed requirement refers to the inadmissibility of restricting the right of Russian citizens to access objective and reliable information."
Where exactly the department sent the demand is also not entirely clear. So, only the account owner can appeal the blocking through a special form. You can also contact @TwitterSupport for various questions.
