Yes a negative effect for obvious reasons.
Here is some more relevant information for how the JWS got banned all over Russia now.
Russian anti-extremism laws were extended to non-violent groups in 2007 and Jehovah’s Witnesses have been officially banned from the port city of Taganrog since 2009, after a local court ruled the organisation guilty of inciting religious hatred by "propagating the exclusivity and supremacy" of their religion.[68]
On December 8, 2009 the Supreme Court of Russia upheld the ruling of the lower courts which pronounced 34 pieces of Jehovah's Witness literature extremist, including their magazine The Watchtower, in the Russian language. Jehovah's Witnesses claim that this ruling affirms a misapplication of a federal law on anti-extremism. The ruling upheld the confiscation of property of Jehovah's Witnesses in Taganrog, and may set a precedent for similar cases in other areas of Russia, as well as placing literature of Jehovah's Witnesses on a list of literature unacceptable throughout Russia. The chairman of the presiding committee of the Administrative Center of Jehovah's Witnesses in Russia, Vasily Kalin, said: "I am very concerned that this decision will open a new era of opposition against Jehovah's Witnesses, whose right to meet in peace, to access religious literature and to share the Christian hope contained in the Gospels, is more and more limited."[69][70][71] On December 1, 2015 a Rostov Regional Court convicted 16 Jehovah's Witnesses of practising extremism in Taganrog, with five given 5 1⁄2-year suspended sentences and the remainder issued fines they were not required to pay.[68]
On May 5, 2015, customs authorities in Russia seized a shipment of religious literature containing Ossetian-language Bibles published by Jehovah's Witnesses. Russian customs officials in the city of Vyborg held up a shipment of 2,013 Russian-language copies of Bibles on July 13, 2015. Customs authorities confiscated three of the Bibles, sent them to an "expert" to study the Bibles to determine whether they contained "extremist" language, and impounded the rest of the shipment.[72]
On July 21, 2015, the Russian Federation Ministry of Justice added Jehovah's Witnesses' official website to the Federal List of Extremist Materials thereby making it a criminal offense to promote the website from within the country and requiring internet providers throughout Russia to block access to the site.[73][74]
On March 23, 2017, the Russian News Agency TASS reported, "Russia's Justice Ministry has suspended the activities of the religious organization calling itself Administrative Center of Jehovah’s Witnesses in Russia due to its extremist activities."[75] The Supreme Court of Russia is scheduled on April 5 to hear a request by the Russian Justice Ministry to declare Jehovah's Witnesses an extremist organization. If adopted, the ruling would ban the organization's activity across Russia and result in seizure of their property.[76] In April 2017, the group was banned, with their property in the country to be confiscated.[77]
