[12][13] The site reflects the work of NGO "Myrotvorets centre", led by a person only known with the alias "Roman Zaitsev",[14] former employee of Luhansk Security Service of Ukraine office.

"[31] The "Myrotvorets" leader states that the centre's objective is to provide information and advice to the executive authorities, to finally bring peace and harmony in Ukraine.

According to them the data of the collected on the website is used in court decisions at all stages - from the beginning of the pre-trial investigation to the conviction of the person, and in numerous rulings, judges also accept information from the "Myrotvorets" as material evidence.

As stated in the website InformNapalm, an important element of the operation was to compare the numbers of Su-24 from the Russian airbase "Shagol" and the same type of aircraft, overturned in Syria.

"[17] In February 2016, members of the centre took part in the operation of mobile groups against illegal transport of cargo through the line of armed conflict in the war in Donbas.

In early March 2016, due to the materials published by the centre, law enforcement authorities in Bulgaria initiated criminal proceedings against George Bliznakov, a Bulgarian citizen.

[36][37] After the site published the data of various journalists, Valeriya Lutkovska, Ukrainian lawyer and Ombudswoman of Ukraine since April 2012, demanded both the website and the Centre be shut down.

[38] On 24 May 2016, Committee to Protect Journalists wrote an open letter to then Ukrainian President Poroshenko urging him to "condemn the unfounded and damaging allegations published on Myrotvorets, and to clarify publicly that the Ukrainian Interior Ministry is dedicated to protecting journalists and apprehending the people responsible for threatening them, in contrast to Interior Minister Avakov's previous statements".

[44] Based on the SeaKrime data, investigations by France Info and Le Monde were able to track some of the stolen grain to Syria after a ship was turned away from Egypt.

[15] Myrotvorets has often blacklisted people over Crimean related issues, which usually means they cannot cross into Ukraine due to the site's usage in border entry checks.

[50] Silvio Berlusconi, Roy Jones Jr, and a number of Russian pop music stars were all added for visiting Crimea, which Ukraine calls an illegal border crossing.

[55] On 11 October 2018, Hungarian Foreign Minister Péter Szijjártó said: "It is a lie that the Ukrainian state has nothing to do with the website that is listing suspected dual Ukrainian-Hungarian nationals", and claimed that President Petro Poroshenko "gave his consent to the hate campaign in an attempt to increase his popularity".

[67][68] Yulia Gorbunova, a senior researcher on Ukraine for Human Rights Watch, said the Myrotvorets list is dangerous as people who have appeared on it have been killed.

[69] In April 2015, Myrotvorets published the home addresses of Ukrainian writer Oles Buzina[70] and former Verkhovna Rada parliamentarian Oleg Kalashnikov, just days before they were assassinated.
