This is not a solution.

The age verification has zero to do with if the pics are safe or not of the tour.

From my understanding it if the site is adult or not for the UK age verification.

If you are outside the UK then why bother to take notice as you are outside the UK legal authorities I would presume and as such they can send you fines but they have no legal powers from my understanding outside the UZk.

So why harm your site when at most they may just block your site from the UK.

Idiot.

This is not just a UK thing... Go back to fucking skulls...

+ Australia

Thank you! What happened to New Zealand? Did they enact the law?

So, the complete list should be:
Countries (ISO 3166-1 codes): AU, DE, ES, FR, GB, GR, IE, IT, KR
U.S. States (2-letter abbreviations): AL, AZ, AR, FL, GA, ID, IN, KS, KY, LA, MS, MO, MT, NE, NC, ND, OH, OK, SC, SD, TN, TX, UT, VA, WY

Please feel free to update it.
