Dvach (Двач), historically Sosach (Сосач),¹⁾ is a Russian bulletin board, founded by “Vitalik” (Виталик) in April 2009, that was sold to Nariman Namazov on September 29, 2010.²⁾ It's often criticized for cooperating with the Russian government since the Mail.ru deal in 2016.

Following the original Dvach's closure, “Vitalik” established a new Dvach successor at “2-ch.ru” using Wakaba around April 6, 2009,³⁾ though users nicknamed it 'Dvatirech' (Дватиреч) or 'Tirech' (Тиреч). The website succeeded, as Mentach and Nullchan had issues, plus it had moderation. However, this iteration struggled with donations, implementing 'VIP tripcodes', and Odinchan proved to be a formidable competitor.

On September 29, 2010, “Vitalik” retired and sold the website to Nariman Namazov, then called “Abu” (Абу).⁴⁾ This new administration immediately gutted the original moderation team, took away 'VIP tripcodes', and changed the board lineup, which meant that the classic 'frames' view no longer supported English or Japanese translations of the Russian board names, presumably to make things easier for them.

In 2011, a new 4chan-like front page was installed, then the website moved to “2ch.so” on April 1, 2011, thus acquiring the nickname 'Sosach' (Сосач). In 2012, a brief DDoS attack around February 4–6, 2012 sent its users to Odinchan, 4chan, or Krautchan, then came a 'meme theft' controversy with VKontakte that led to a massive shitstorm after Sosach voluntarily decided to advertise itself to the MDK community.

“We've had a domain in Somalia for a long time, but the local authorities (lolwut, didn't know they were there) took the domain down because of a demotivational poster. I tried to phone them, but it didn't help.”
– Nariman Namazov⁵⁾

By late 2013, the “2ch.so” domain was suspended for violating Somalian internet law,⁶⁾ so they held “2ch.ek” for a week, then settled at the “2ch.hk” domain. The website then brought back paid services, as the 4chan Pass justified its existence, and managed to add WebM support. However, the increase in users eventually bog down its heavily-modified Wakaba fork, then called “Wakaba v3.0.8-mk2”.

On August 2, 2014, they replaced the Wakaba fork with Makaba, making the website “ten times faster”,⁷⁾ and several advancements followed (e.g. ability to upload four files, new mobile API, favorite/hide threads, etc.). They also took inspiration from 8chan, allowing user-created boards, and overhauling the front page to match. By 2015, an official VKontakte page was established, which was, then, a controversial move.⁸⁾

In 2016, CloudFlare sent an email on September 14, 2016,⁹⁾ intending to spike their bills from $200/mo to $3,000/mo,¹⁰⁾ so the website went down on September 24, 2016 as they couldn't afford DDoS protection.¹¹⁾ Some users fled to BRchan (later Lolifox) or Dobrochan. After some time, the “2ch.pm” mirror allowed posting to resume, then came the controversial Mail.ru deal on September 30, 2016.¹²⁾

“Now, regarding Dvach, before posting about the *RKN-prohibited word* operation, think ten times about what you write if you're posting from Russia.”
– Nariman Namazov¹³⁾

From this point onward, some users held the opinion that the website was 'compromised' as they cooperated with the Russian government. In 2017, MP4 support was added, then they changed the CAPTCHA to reCAPTCHA. The following years seems to have been unremarkable, besides the brief Chinese New Year wordfilter event during the pandemic in 2021, poking fun at Russia and China's similarities.

In 2022, the Russian intervention naturally became a hot topic. Some liberals and Ukrainians kept posting 'extremist' statements on “Politics” (/po/) and self-report to the authorities, which forced them to temporarily restrict the board around October 22, 2022. During this period, the CAPTCHA kept being reworked, sometimes causing CloudFlare to return HTTP 429 or HTTP 500 errors.

Around February 22, 2023, a few founding 'gay' boards¹⁴⁾ were reportedly blocked.¹⁵⁾ A few months later, the “Ukraine” (/ukr/) board had some of its moderators removed for 'extremist' statements, so the users fled to Dollchan on May 19, 2023,¹⁶⁾ then it was deleted on September 30, 2023 and its users were then redirected to “Novorussia” (/nvr/). On December 11, 2024, Namazov registers “Dvach Media LLC”.¹⁷⁾
