This seems like an insanely hard problem with many false positives/negatives. But of course the media hysteria against tech and fake news might eat it up and praise twitter. Nice PR move for non techies.
> Nice PR move for non techies. Depends if the praise they get for "at least they're doing something/not pretending the problem doesn't exist" outweighs the criticism they get for false positives, false negatives, inconsistency/bias, arbitrary judgements, response times, or labelling so many things fake that it becomes meaningless. Way back in 1994, Time magazine published a photo of OJ Simpson that was photoshopped…
Meanwhile, there was an a very convincing deceptively-edited video circulating on Twitter which clamed to show parts had been sped up by overlaying the White House version on the original - it was very vivid, with the overlay seeming to jump ahead in fast-moving parts. This was an illusion created by running the videos 7 frames or so out of sync the whole way through and abusing the fact the slight differences weren't noticable in slow-moving parts during normal playback. No-one noticed. Youtube fighter of misinformation Captain Disillusion even helped spread it and gave his approval.
My general reckoning is that Twitter would get much more praise for labelling the non-tampered video as misleadingly edited and endorsing the accuracy of the video that was misleadingly edited to make the other one appear that way, than the other way around.
