I redirect traffic from blocked states to this page…

That entire site is porn-related, minus the actual porn.
The state doesn't know what sites you're viewing. The laws don't criminalize viewing porn, they criminalize publishing porn. Most of the laws don't even give the states jurisdiction over enforcement (because that lets the porn industry preemptively sue the state). Instead they let (MAGA, Christian Nationalist) parents sue porn sites for perceived "harm" the porn site did to their child when the child encountered porn because the parent failed to do their job of putting appropriate content filters on their kid's device. So basically the laws reward people for being bad parents.
And no, websites are not exempt from laws just because they're located elsewhere. That's how it should work but everyone wants to pass laws that apply to people outside their jurisdiction, so websites have to follow the laws where their visitors are, not where they are. Technically that means I violate the laws where homosexuality is illegal and could be tried in those countries. But those countries going after people like me is pointless since the US would never extradite me to face trial, and I avoid those countries…
