I registered as an adult on an online service by using the photo mode in a video game, to take a picture of a character, then used that picture on the webcam to say I'm over 18 ✅
This works via the services which let you verify your face via your phone btw, just put the game into photo mode and then move the character or camera around as requested.
Brits can get around Discord's age verification thanks to Death Stranding's photo mode, bypassing the measure introduced with the UK's Online Safety Act. We tried it and it works—thanks, Kojima

The UK's new act blocks access to adult content without identification. Turns out, you only need a copy of Death Stranding and a phone to get around it.
