Apple iOS now requires age verification to access websites it deems 18+. Not even using another browser like Firefox works, it's blocked at the OS level.
I was putting off switching to Graphene or e/os until prices improve, but looks like my hand is forced.
Edit: VPN doesn't even work because Apple knows your GPS location. I haven't tried location spoofing yet because that's a bit more annoying to setup.
You should try Gemini. The name came first than the AI from google. It's a mostly text based internet you can't access with a regular web browser. Basically, all links start with "gemini://" instead of "http://".
