BRUSSELS — The European Commission has added XXNX to its list of platforms designated as “very large online platforms” (VLOPs) and therefore subject to special regulations under the controversial Digital Services Act (DSA).

XXNX joins Pornhub, XVideos and Stripchat on the list, all of which were initially designated in December, as XBIZ reported.

The DSA classifies platforms that reach at least 45 million average monthly active EU users as VLOPs. In an official announcement, the Commission stated at the time that its investigation had determined that the three adult sites meet that threshold.

In March, European tech news site Euractiv reported that the Pornhub, XVideos and Stripchat were suing the EU over their classification as VLOPs.

Last month, the EC — the European Union’s executive branch — asked the three companies to “provide more detailed information on the measures they have taken to diligently assess and mitigate risks related to the protection of minors online, as well as to prevent the amplification of illegal content and gender-based violence.”

The EC said XXNX “must comply by November with the extra measures, including preventing minors from accessing online porn by using age verification tools, as well as giving researchers access to publicly available data and publishing an ad database,” Associate Press reported.

“XNXX must also duly assess and mitigate any systemic risks stemming from their services, such as risks related to the dissemination of illegal content, or the negative effects on mental and physical well-being of the user,” the EC explained in a statement.
