The DSA requires internet companies and online platforms to protect users or else face fines that can go as high as 6 percent of a company’s global annual revenue.
The commission said it would carry out an in-depth investigation into the four adult content providers “as a matter of priority.”
The investigation will focus on the risks to the protection of minors, including dangers associated with the lack of effective age verification measures.
It said the porn sites have failed to put in place “appropriate and proportionate measures” of safety and security for minors, especially when it comes to age verification tools designed to prevent minors from getting to adult content.
The sites also lack “risk assessment and mitigation measures” of any negative effects, including on users’ mental and physical well-being, the commission said.
The four sites were classed as “very large online platforms,” meaning they are subjected to the highest level of scrutiny under the DSA.
Pornhub and Stripchat are both based in the EU member state of Cyprus, while XNXX and XVideos both operate out of the Czech Republic, which is also part of the bloc.
Stripchat’s obligations as a “very large online platform” will cease to apply in four months’ time, at which point it will be monitored by the Cyprus Radiotelevision Authority, where the site is based.
“Together with the Digital Service Coordinators in the member states, we are determined to tackle any potential harm to young online users.”
The commission also said the bloc had begun working on its own age-verification app that online platforms can use to verify a user’s age without revealing any other personal information.
The wallet would, according to the commission’s website, “enable users to access online and offline public and private services, store and share digital documents, and create binding signatures,” and be made available to all citizens, residents, and businesses within the bloc.
Pornhub’s owner, the Cyprus based group Aylo Freesites, told The Epoch Times it was aware of the investigation, that it is “fully committed to ensuring the safety of minors online,” and that its sites were fully restricted to adults only.
“We will always comply with the law, but we hope that governments around the world will implement laws that protect the safety and security of users,” it said.
“We believe that the real solution for protecting minors and adults alike is to verify users’ ages at the point of access—the users’ devices—and for websites to deny or permit access to age-restricted materials based on that verification.”
The Epoch Times has also contacted all the owners of Stripchat for comment, but has so far been unable to contact XVideos’ and XNXX’s parent companies.
