Yes, an age verification law has been enacted in my country a while ago. Not every website is requiring it yet, since it's slowly being implemented, but some websites have been preemptively requesting age verification even before the law went into effect, like onlyfans. My concern would be going through the signing up and payment process, and only being asked to verify my age when I try to access the content. And refund requests here are a bitch to go through.
