Due to the UK’s new online safety act, it is now a legal requirement for websites featuring adult content to provide age verification for all UK visitors using a form of ID.
That level of verification is not only outside the scope of this website, but is something you should be uncomfortable doing just to have the right to view completely legal material that you have always had the right to view until now.
However, this website is available to everyone else on the rest of the world, so it is highly suggested that you go and get a VPN to bypass this restriction and not have your internet usage restricted by condescending and out of touch internet regulation.
