A gentle reminder that, if you run a regulated user-to-user service within the scope of Part 3 of the UK's #OnlineSafetyAct, which falls within the requirement to put in place highly-effective age assurance (which does not apply to all services), you have just a few more days - until 25 July - to do so.
If you are not sure, start with a child access assessment, and then, if needed, a child risk assessment.
Most problematically, I have zero recommendations for a tried-and-tested, Free / open source, data protection compliant, age assurance system.
If you cannot implement age assurance, you might want to look at ways to lessen the risk, to escape the requirement.
