Investigation into

ZD Media s.r.o.

Case opened

10 September 2025

Summary

We are investigating whether ZD Media s.r.o. has failed, or is failing, to comply with its duties under the Online Safety Act 2023 to prevent children from encountering pornographic content on its service through the use of highly effective age assurance.  

Relevant legal provision(s)

Section 12 and section 81 of the Online Safety Act 2023

Following an investigation, Ofcom has provisionally determined that there are reasonable grounds to believe that ZD Media s.r.o. (‘ZD Media’) has failed to comply with section 12 and section 81 of the Online Safety Act 2023 (‘the Act’).

Section 12 imposes a duty on providers of Part 3 services that allow pornographic content, and that are likely to be accessed by children, to ensure that children are prevented from encountering pornographic content on the service through the use of highly effective age assurance.

Section 81 imposes a duty on providers of Part 5 services to ensure, through the use of highly effective age verification or age estimation (or both), that children are not normally able to encounter regulated provider pornographic content.

Ofcom therefore issued a provisional notice of contravention to ZD Media on 3 September 2026 under section 130 of the Act.

The notice sets out the facts that Ofcom has relied upon to reach its provisional view, the actions we propose to take, and the rationale for those decisions. ZD Media will now have a period of 20 working days to make representations to Ofcom, which will be carefully considered before reaching a final decision.

On 10 September 2025, under our enforcement programme to protect children from encountering pornographic content through the use of age assurance, we opened an investigation into ZD Media s.r.o. in relation to the following adult services it operates: www.hello.porn, www.homo.xxx, www.max.porn, www.ok.porn, www.ok.xxx, www.perfectgirls.xxx, www.pin.porn, www.pornhat.com, www.pornhat.one and www.pornstars.tube. As part of our investigatory process, if we identify further adult services operated by ZD Media s.r.o. that fall within the scope of the Act, we may expand the investigation to include those services.

Ofcom’s investigation will examine whether there are reasonable grounds to believe that the provider has failed, or is failing, to comply with its duties under section 12 of the Act, to prevent children from encountering pornographic content through the use of highly effective age assurance. These duties have applied since 25 July 2025.

In addition, or in the alternative, this investigation will also consider ZD Media s.r.o’s compliance with section 81 in Part 5 of the Act to prevent children from encountering pornographic content through the use of highly effective age assurance, as applicable.

Ofcom’s Online Safety Enforcement Guidance sets out how Ofcom will normally approach enforcement under the Act. This includes our approach to information gathering and analysis and the procedural steps we must take to fairly determine the outcome of the investigation.

We will provide an update on the investigation in due course.
