Reddit users in the United Kingdom will now be blocked from accessing “certain mature content” unless they complete the platform’s new age verification process. Reddit announced on Monday that UK users will need to upload a selfie or a photo of their government ID in order to view content that’s restricted for under-18s by the UK Online Safety Act (OSA),

Reddit will use the third-party service Persona to confirm a user’s age, necessitating users to submit a picture of their government-issued identity documents or take a selfie. Reddit said it will not have access to these images, and will only save the person’s verification status and their date of birth.

Redditors in the UK will now have to verify their ages before they can view mature content. Just like Bluesky, which announced a few days ago that it was rolling out age verification features, Reddit had to enforce the new rule to comply with the UK Online Safety Act.
