FYI, with Mullvad VPN set to UK, sites that require age verification:

• pornhub.com
• youporn.com
• redtube.com
• porn.com
• bellesa.co
• tube8.com
• thisvid.com
• quorno.com

Sites tha do NOT require age verification:

• hqporner.com
• xhamster.com
• youjizz.com
• alohatube.com
• qqqporn.com
• xnxx.com
• xcafe.com
• helloporn.co
• go.porn
• cartoonporn.pro

And xvideos.com is a bit special since it shows you the thumbnails of porn videos but won't let you play them.

But we need to stop VPNs! Think of the whole two children that have VPNs! What if instead of just going to the half of the sites that don't verify age, they figure out how to use a VPN?! Oh the humanity!

Yeah, UK wants to de-anonymize VPN users as the next step in their attack on free speech. It is laughable to think this is about anything else.
