In February 2008, British company I-CD accused Albert Popkov of violating their copyright. According to I-CD, Albert Popkov as an employee of I-CD worked on their projects and Passado until his resignation in November 2005. In December 2006 the company raised €10 million to expand Passado in Russia.[9] Albert Popkov allegedly used the proprietary information to create his own site very similar to Passado. He denied those allegations,[10] but was later dismissed as Managing Director by Odnoklassniki[11] and in November 2009 after the first day of trial in the Royal Courts of Justice[12] in London I-CD completely dropped all charges against Albert Popkov and Odnoklassniki[13] after Albert Popkov and Odnoklassniki agreed to pay i-CD an undisclosed amount of cash in settlement of the case against them.

On September 15, 2008, Vedomosti reported that Albert Popkov, founder and key shareholder in Odnoklassniki had sold a controlling interest in the network to Digital Sky Technologies (DST), the owner of DST and its subsidiary Forticom together control 58% of the network.[14] On the previous day it was announced during a news conference that the network's interface would be translated into Azerbaijani.

In May 2017, Ukrainian President Petro Poroshenko signed a decree to impose a ban on and its widely-used social networks including VKontakte and Odnoklassniki as part of its continued sanctions on Russia for its annexation of Crimea and involvement in the War in Donbass.[15][16] The move was widely criticised as censorship, and Reporters Without Borders condemned the ban, calling it a "disproportionate measure that seriously undermines the Ukrainian people’s right to information and freedom of expression."[17][18] Respondents in an online poll on the UNIAN site declared that 66% were “categorically against” the ban of Russian sites and another 11% said it would be easier to “ban the whole internet, like in North Korea”.[19]
