Sorry, I'm not sure I understood you: did you mean that a click-through warning that somewhere on the site there is adult content was all we needed?

I was hoping to develop a solution more granular than that, so that readers who would be triggered by or who would be violating the law of their nations by looking at some sorts of explicit content could still use the site. A single click-through warning before you entered the site to begin with wouldn't really be that useful for them. Or did I misunderstand you?
