Another difference between .xxx and a safe hint is that there would or could be an authority judging the content that does or does not go under .xxx. With a safe hint, that distinction is drawn by the content holder. I think a safe hint is a far more workable solution as there would never be a universal agreement about what constitutes .xxx material (as is stated by 3675). > > The privacy issue described in RFC 3675 would also appear to be avoided, at > least up to the point where a sufficiently high number of requests use the safe > hint that requests without it stand out.

Perhaps this draft could have an informative reference to 3675 if readers want to know more about the issues of what is and is not "safe" content. But I don't see the issues discussed in 3675 as being showstoppers for this. And given this draft is documenting an existing practice, I support its adoption. -andy
