> You are, generally, supposed to put the new answer on the old question
If you're asking the question, you don't know the new answer.
If you're not asking the question, you don't know the answer needs updating as it is 15 years old and has an accepted answer, and you didn't see the new question as it was marked as a dupe.
Even if you add the updated answer, it will have no votes and so has a difficult battle to be noticed with the accepted answer, and all the other answers that have gathered votes over the years.
I won't hold my breath. It'll take 5 times longer than planned, cost 10 times more, won't do everything it originally set out to do, then won't work on the tech that everyone will have when finished, and a future government will decide they don't like it and will start over.
By default for me (in the UK) it still seems possible to view porn in a Google image search in an incognito browser tab. I don't think non technical parents can be expected to change their DNS settings to something safe to block it. I'm a bit unclear as to what the online safety bill is solving if Google can ignore it.
I 100% agree that today expecting average parents to manage DNS is unreasonable. My point is that sites need to provide some sort of consistent way for inappropriate content to be identified, then software will evolve to make it easy for non-technical parents to apply the restrictions.
"Flatten" comes from the world of desktop image editors. You "flatten" one layer down to the next to make one layer. Sometimes the people who work on these kinds of things forget their users might have never used software with metaphors like this.
So do these collectors have the ability to play back these recordings? If so, could they at least make some recording (even if pointing a camera while playing back would be better than nothing) to send to the BBC.
Otherwise if they have no means to play it back, I fail to understand why they'd not want the opportunity to watch their collection!
