18+ age verification pop-ups and new laws?

[PatriotGB]

I'm seeing more and more sites with "18+" pop-ups. And I'm hearing rumblings about such requirements for "social media" sites.

Now... my forum's registration process already includes a birthdate question and screens for 18+ (built-in to XenForo).

But, I'm seeing (and talking about) pop-ups just to VISIT forums or websites as a visitor.

If this comes to be, or already "do be," how can I set that up - if need be.

Thanks!
