Dear OnlyFans: What the heck are you doing? Sincerely, the internet.

Usually, when a social media platform tightens its grip on sexually explicit material, netizens generally nod along. 

That wasn’t the case for OnlyFans, the social media company that allows creators to sell their content on subscription. Its Thursday decision to ban sexually explicit content beginning in October ignited panic among its user base and elicited raised eyebrows from many on Twitter. Unlike say TikTok or Instagram that appealed to a broader audience, OnlyFans had found much popularity in a very specific though very lucrative part of the internet: In selling sex.

OnlyFans made hundreds of millions last year in part due to sex workers who flocked to the platform during the depths of the pandemic. Now, as it turns against sexually explicit content, creators on the platform that helped make it so successful feel as if they’ve been used and thrown aside. And it raised another question too: Will the platform survive without sex?

One important note of clarification: OnlyFans is still allowing nudity on its site as long as it is consistent with the company’s policies. Which means users are still waiting for the company to define the line between nudity and sexually explicit content.

Still, this broad turn against pornography by a social media company immediately drew comparisons to another company that made a similar pivot several years ago and fizzled out as a result: Tumblr. Once valued at as high as $4.5 billion, Tumblr banned adult content in 2018. But unfortunately, users were coming to Tumblr for its titillating posts, and it lost a third of its users a year later. 

Meaning from a historical point of view, OnlyFans’ decision is a fraught one—one that has led to an exodus of users in the past. 

So why fix something if it isn’t broken? In its Thursday statement announcing the ban, OnlyFans said the “changes are to comply with the requests of our banking partners and payout providers” without naming said providers and partners. 

And this is where it gets kind of weird. Sure, banks and payments companies have historically been wary of the porn industry, with Mastercard in April demanding verification of age and consent from adult content sellers.

But Mastercard on Thursday said it had not been in conversations with OnlyFans preceding the ban. “We found out about this through the media coverage. This appears to be a decision they came to themselves,” Seth Eisen, senior vice president of communications at Mastercard, wrote in an email to Term Sheet. Visa and Discover meanwhile have yet to respond to requests for comment.

Axios on Thursday provided another potential explanation that may have driven the ban: The company might be rolling in dough, but it has struggled to find investors willing to take a cut in the company in part due to its explicit content. Some venture capitalists are in fact unable to invest in such businesses due to so-called vice clauses that bar funds from putting dollars in industries around say sex and tobacco.

Then the BBC also published a report on the same day alleging that the company has lax moderation policies that have allowed illegal content, including those featuring minors, to appear.

All of this puts OnlyFans in a really messy position: It’s trying to go mainstream, and even kicked off promotions for a safe-for-work app this week. The ban could certainly address the issue of illegal pornography on its site—but users also say it could be kicking legal sex workers to the curb and raises the question as to whether OnlyFans is sending off its own biggest fans.
