All you can do is take FB at their word that the image is destroyed irrevocably. Given what we know about data retention policies at big tech firms, I'm not so sure I would feel confident taking the press release at face value. I'd really like to see a white paper or similar outlining the specifics of how this is being handled. I'd also have questions around what steps have been taken to prevent rogue Facebook employees trying to obtain the images. I really wish they had found a way to generate the hashes they require client side and not receive the image at all, especially as this is something that presumably would be really great for revenge porn victims.
