If this becomes a bit more widely used, aggregating information about the contexts where it’s more (or less) used would be very interesting. At the moment I suspect nobody has decent-quality stats about the incidence of legal blockages - I mean civilized-process-of-law legal blockages, not the censors working for oppressive governments, who won’t be using 451 anyhow. >> > > Why wouldn’t they? You’re talking as if their shady organizations blocking content in a society that otherwise abhors censorship. They’re not. They’re out in the open, and this status is one way to tell their citizenry that they’re getting too close to forbidden content. > > The reason they’re not likely to use 451 is for the same reason you hardly ever see the 404 status code. They don’t want to emit some status code that will give you a blank page. They want to show you a scary page with official logos telling you to get away from the evil content and reminding you of what happens to people who get caught with content like that. Sorry, what? 404s are sent all the time; browser display the body just as they would for a 200. Likewise for 451 (and this has been tested). As I said, I've talked to some content folks who are interested in producing this status code. Hopefully, they'll put their .02 in when we do a call for adoption.
