Tesak first gained public attention as a white power skinhead and the leader of the far-right youth group Format 18, which has been described as the "armed wing" of the National Socialist Society.

There are numerous branches within Martsinkevich's Restruct movement, the most prominent of which is Occupy Pedophilia, with Tesak having stated that its goals are the promotion of national socialism, identifying the nature of liberal views, and drawing the public's attention to the issue.

On 27 June 2017, the Babushkinsky district court of Moscow sentenced Martsinkevich to ten years in a strict regimen corrective labor colony for his involvement in attacks targeting synthetic cannabinoids dealers.

As expressed in his first autobiographical audio book Destruct, his mother did not share her son's extremist views while his father was supportive.

[2] Martsinkevich was conscripted into the Russian Army, although he claimed that he was released after a few days, following a mental health evaluation caused by him having beaten up a fellow soldier of Azerbaijani ancestry.

[8][11] One of the publicly available Format 18 videos called "Dacha History X" depicts a skinhead dressed as an old woman who hates black people, with her grandson burying them in the garden.

[15] The Russian newspaper Novaya Gazeta published an opinion piece stating that investigators ignored the worst cases of this neo-Nazi's criminal activity, thus leading to the mild punishment.

[citation needed] In 2006, 20 people dressed as members of the Ku Klux Klan staged the execution of a Tajik drug dealer, filming and releasing it on the Internet.

The court gave Martsinkevich credit for good conduct and adjusted the sentence to three and a half years in prison starting from the first conviction.

[citation needed] After getting out of prison Martsinkevich started the Occupy Pedophilia (Russian: Оккупай-педофиляй, romanized: Okkupay-pedofilyay) movement focused on beating up and humiliating males regarded as pedophiles.

Then a group of people met the alleged pedophile and humiliated him, sometimes pouring urine over his head, while filming it for release online.

Actions of members of both of the branches have also been described as campaigns against LGBT people, with one Occupy Pedophilia local group leader saying that "practically all gay men [are] pedophiles".

Martsinkevich said that the indictment was ordered by the "pedo lobby" seeking revenge, mentioning the official Andrey Kaminov he caught during a date with a minor organized by Maxim.

The prosecution argued that the defendant has shown three videos with extremist content and psychological threats made by Martsinkevich on his personal page on the social network Vkontakte.

Tesak was found guilty of the attacks - one having resulted in death, and on 27 June 2017, judge Alexander Glukhov sentenced Martsinkevich to 10 years in a strict regimen labor colony, beginning on 27 January 2014.

[citation needed] On 21 May 2018, it was reported that the Moscow City Court overturned the 27 June 2017 conviction and requested another hearing, while leaving Martsinkevich incarcerated.

His fellow neo-nazi Sergey Korotkikh (nicknamed Malyuta) stabbed one of them with a knife, which resulted in Martsinkevich getting arrested by the police on the suspicion of hooliganism.

One of Martsinkevich's lawyers made a public statement in October 2014, saying that his client had been charged with hooliganism for cutting off a man's hair.

[24] In November 2014, Tesak was charged with inciting ethnic hatred for writing and publishing his book Restruct, which has been classified as extremist.

[24] The investigation of the above-mentioned murder of a Tajik and a Dagestanian gradually led to Maxim Martsinkevich, who was at that time (2020) serving his fourth prison sentence.

[25] Eventually, despite all the confessions made by Martsinkevich and others, the investigation against him was closed in the beginning of 2023 at his father's request, due to the death of the suspect.

[2] On 16 September 2020, Martsinkevich was found dead with signs of torture in a pre-trial detention centre in the Chelyabinsk region, reportedly from taking his own life.

The note was reported to have contained a request for officials to give a private diary and a book on communism to Martsinkevich's wife in Yekaterinburg.
