PornHub compared minute-to-minute traffic on their site before and after the missile alert to an average Saturday (okay for work). Right after the alert there was a dip as people rushed for shelter, but not long after the false alarm notice, traffic appears to spike.
Some interpret this as people rushed to porn after learning that a missile was not headed towards their home. Maybe that’s part of the reason, but my guess is that Saturday morning porn consumers woke earlier than usual.
