Reduxx reports that 46-year-old Marius Gustavson made £200,000 by posting the illicit surgeries to his website entitled "Eunuch Maker" to a subscribing audience after he moved from Norway to England. On his website, he offered “free castration performed by the EunuchMaker.”
Last year, the World Professional Association for Transgender Health (WPATH) released its Standards of Care Version 8 (SOC8) which stated “Eunuch individuals are those assigned male at birth (AMAB) and wish to eliminate masculine physical features, masculine genitals, or genital functioning” it explains. “As with other gender diverse individuals, eunuchs may also seek castration to better align their bodies with their gender identity. As such, eunuch individuals are gender nonconforming individuals who have needs requiring medically necessary gender-affirming care."
Gustavson had also confessed to possessing criminal property, referring to the money he made from illegal content, and separately pleaded guilty to making and distributing two indecent videos of a child between January 2017 and January 2020 to Old Bailey Criminal Court in London.
A bulk of Gustavson's followers on his multiple social media accounts were made up of trans-identified males. Many allegedly had strong interests in chastity fetishism, eunuchdom, and a fetish body modification subculture dubbed "nullification," which describes the desire to practice or watch the removal of male genitalia.
Many of his followers called themselves "nullos" or "smoothies" and Gustavson himself, who also went by "Theo," was self-described as a "happy nullo."
His social media account handles were @nullotheo, @ampunullotheo, @chubtheo, and @theo-eunuchmaker.
He was arrested with 6 other men in February 2022 after he enlisted the help of registered nurses, and even a surgeon, to perform amateur amputations on himself and 58 other men, utilizing their access to surgical tools and medical supplies. Gustavson admitted he kept amputated genitalia in a freezer and preserved in alcohol in his basement.
He is said to have been the ring leader of a larger network of men who performed fetishistic amputations and other procedures for sexual gratification, many who have also been charged and convicted.
From 2001-2007 Gustavson was Chairman of the Board for the Buskerud chapter of The Norwegian Organization for Sexual and Gender Diversity, now known as FRI (foreningen for kjønns- og seksualitetsmangfold). The organization, according to Reduxx, "had been working to remove sadomasochism as a paraphilic diagnosis from the ICD since 1996" and in 2018 "successfully lobbied the World Health Organization to officially depathologize fetishism, sadomasochism, and fetishistic transvestitism by removing them from the 11th revision of the International Classifications of Diseases and Related Health Problems (ICD-11)."
