Blocking attempts In August 2015, the /g/ ("naked girls") board was blocked in Russia after alleged posts of child pornography. In May 2017, Dvach was blocked in Ukraine, along with other services hosted by the Mail.Ru Group. In November 2019, Russian Internet regulators demanded that Dvach delete posts degrading state symbols, and threatened the site with blocking. Dvach's official Twitter account was blocked on 14 March 2020. Representatives said it was due to copyright infringement on the new account, but users speculated that it was related to a conflict with Russian feminist activists. In March 2020, Dvach was temporarily blocked due to COVID-19 misinformation. Hacking cases Back in 2011, Dvach users were accused of DDoS attacks against opposition websites. After the Kerch Polytechnic College massacre, the perpetrator's (Vladislav Roslyakov) accounts were hacked and his direct messages were posted on Dvach. He gained a lot of fans on the site.

He placed a link to 2ch.hk accompanied by the Yoba meme. Doxxing pornstars Dvach is often criticized for their attitude towards women. In April 2016, Dvach users doxxed Russian porn actresses, outing them to their friends and families. They used FindFace, a face recognition service that searched in the photos uploaded on VK. In early 2020, Dvach users doxxed Russian women who participated in a porn-horror video by Till Lindemann, a Rammstein vocalist. The users criticized them for "degrading the image of Russian women".
