It takes a nation to protect the nation
This Muslim site reports that it did. The site links to a Russian language site. Nobody else seems to have reported it.
What is banned seems to be just the Russian translation of the Quran. If that is correct then they are targeting non-Arabic speakers. While this would slow conversions down it would at the same time make the understanding of the Quran only accessible to those same Arab speakers. Dawa would continue but without the scrutiny from the potential convert. Muslim converts would still recite the Quran but would have less opportunity to understand what they are saying. I know of Muslims who have left Islam once they realised exactly what they were reciting.
If the Russian State is now clearly saying : "The Koran calls for hostile and violent acts of one group of people against another on the basis of religion, in this case, Muslims against non-Muslims", then what is required is a process to explain this teaching and to draw people away from Islam and further strengthen the populace from the attractions of Islam. An office of counter-Islam propaganda based on this truth would be a natural and necessary tool to de-Islamise Russian.
Can anyone else offer more information?
"A Russian translation of the Koran is now officially banned by the KGB. According to Russian media, on September 18, an "October district court" in the Russian-occupied Emirate city of Tsemez ("Novorossiysk") banned reading "The semantic translation of the Holy Koran into Russian" (translated from Arabic by E.R. Guliyev. 1st edition. King Fahd Complex for Printing of the Holy Koran, Medina, Munawwara, Saudi Arabia, 2002).
"According to the KGB court, the Koran is "extremist literature" under the Russian Criminal Code article # 282. "The Koran calls for hostile and violent acts of one group of people against another on the basis of religion, in this case, Muslims against non-Muslims", the KGB court ruled. According to Russian federal laws, it is now forbidden to read the Koran translation all over Russia, and keeping it at home is a criminal offense.
"It is interesting to note that this unprecedented act of war on Islam remained virtually unnoticed by the media. Russian as well as western media outlets ignored the ruling of the KGB court. So-called muftis and various Muslim organizations in Russia are also silent.

Ravil Gainutdin, the head of the Council of Muftis of Russia, said in an open letter to President Vladimir Putin released Monday that the ruling was "illiterate" and "provocative."
The Quran is available in Russian translation, but the court last week ruled that the translation by Elmir Kuliyev published in Saudi Arabia in 2002 violated federal law banning extremist materials.
Gainutdin said that the "Russian Muslims were appalled by the neglect of law shown by the court" in the Black Sea port of Novorossiisk and demanded that the verdict be revoked. He said the court's order to destroy the Muslim holy book was particularly outrageous.
