From the FTC website, they wrote:
The settlement bars the defendant from displaying sexually explicit ads to consumers unless the consumers are actively seeking out sexually explicit content or unless the consumers have consented to viewing sexually explicit content....
So if a web surfer visits an adult website that has the warning labels that it is an adult site, and they enter the website as an adult to view adult material.. how can there be obscenity charges anymore?
If the adult content was in the open (like you see on some paysites, TGP, MGP, etc)... that's one issue where people who stumble upon those images, but in circumstances when an adult choose to view content...
Maybe the adult lawyers can use this case to help in obscenity issues.
