OnlyFans was founded in 2016 by a British entrepreneur named Timothy Stokely, now 37, alongside his retired banker father, Guy Stokely, and brother Thomas. In October 2018, Florida-based internet porn baron Leonid Radvinsky, now 39, bought an estimated 75% of the company. With all film production – adult or otherwise – shuttered during the pandemic and millions of lonely people stuck at home, OnlyFans’ business has boomed. In the year through November 2020, OnlyFans posted revenues of $400 million, up 540% over the prior year, 80% of which came from American customers. The number of creators nearly quintupled to 1.6 million, including more mainstream stars like Cardi B, DJ Khaled, Fat Joe, and Rebecca Minkoff. The total number of paying fans rose more than 500% to 82 million. Profits after tax rose to $60 million from $6.6 million. Forbes estimates that Radvinsky’s stake in Fenix International – OnlyFans’ parent company — makes him a new billionaire, worth some $1.8 billion. Some twenty years ago, before Internet pornography was widely available for free, he ran a small empire of websites that advertised access to “illegal” and “hacked” passwords to porn sites, including ones that were advertised as featuring underage performers. In the late 1990s such link sites were common and were used to market not just pornography but online gambling and other grey market activities. There’s no evidence that any of Radvinsky’s sites actually linked to child pornography or bestiality. Instead, the sites appear to have been a way for Radvinsky to earn money by charging his partners (actual porn sites) for every click. Forbes, prohibited from accessing such imagery, asked the Internet Watch Foundation (IWF), a specialist group engaged in the removal of such content on the web, to look at archived webpages containing links advertising underage pornography. According to the IWF, none linked to illegal material. In the early 2000s, he created a handful of sites linking to celebrity sex tapes and MyFreeCams, a site that claims to be the world’s number one porn-via-webcam service. He has also occasionally popped up in lawsuits. In 2003 and 2004, Amazon and Microsoft sued Radvinsky in U.S. district court in Seattle for alleged spam campaigns that used the Amazon name and Microsoft email tools to offer spam recipients “free money from the government” or links to adult websites. Radvinsky denied all allegations. The cases were settled out of court in 2005, and Radvinsky and his businesses were barred from using Amazon’s name in spam or using any of Microsoft’s email tools. His Cybertania business was sued in 2005 by a model, Sheila Lussier, for using her (clothed) image on one of his porn sites, an allegation the company fought. Lussier says she settled for an undisclosed sum. OnlyFans has run into its own issues with underage performers. Since the site doesn’t independently verify its sex workers’ ages, it’s fairly easy for people to lie. In late May, a BBC investigation revealed that a 14-year-old girl had been able to register an account as a performer on OnlyFans using her grandmother's passport. A senior police officer told the BBC that OnlyFans is “[N]ot doing enough to put in place the safeguards that prevent children exploiting the opportunity to generate money, but also for children to be exploited." In response, OnlyFans issued a statement that it used “state-of-the-art technology” and “human monitoring” to try to prevent under-18s sharing content on the platform and it took the issue “very seriously.” Signy Arnason, associate executive director of The Canadian Center for Child Protection, says her group often receives notifications about OnlyFans’ models potentially being underage. She describes OnlyFans’ efforts to protect underage performers as “minimal.” OnlyFans has “a moral and ethical responsibility to be doing better here,” she adds.
