Schedule 12: OFCOM’s powers of entry, inspection and audit Chapter 5: Regulated user-to-user services and regulated search services: notices to deal with terrorism content and CSEA content Section 121: Notices to deal with terrorism content or CSEA content (or both)
Chapter 5 provides the statutory basis for OFCOM’s power to require a service provider to use accredited technology to tackle terrorism content and child sexual exploitation and abuse (CSEA) content and/or develop and source technology to tackle CSEA content.
	Subsection (1) sets out that OFCOM may issue a notice to a service provider of a regulated user-to-user service or a regulated search service, when doing so is necessary and proportionate.
	Subsections (2)(a) states that OFCOM may require a service provider of a regulated user-to-user service to use accredited technology to identify terrorism content communicated publicly (as defined in section 237) and/or CSEA content on any part of the service. The service must take down that content without delay. The service may also be required to prevent this content from being made accessible to users at the outset, so that they do not encounter it, for example by preventing the content from being uploaded onto the platform.
	Subsection (2)(b) states that OFCOM may require a service provider of a regulated user-to-user service to use its best endeavours to source or develop technology to identify and remove CSEA content on any part of the service or to prevent users from encountering this content. This technology must meet minimum standards of accuracy.
	Subsection (3) states that OFCOM may issue a notice under this section to search services, and subsection (4) makes clear that any notice given under subsections (2) or (3) can be issued to a provider that has both user-to-user functions and search functions.
	Subsection (5) states that in removing terrorism or CSEA content under subsections (2) and/or (3), providers may solely deploy accredited technology, or a combination of accredited technology and human moderators.
	Subsection (6) refers to section 122, section 123, and section 124, which set out the process hat OFCOM must follow in issuing a notice to a service provider as set out in subsection (1) and states that OFCOM must issue a warning notice before issuing a notice under this section.
