The BBC reports that the UK-based Internet Watch Foundation is sharing hash lists with Google, Facebook, and Twitter to prevent the upload of child abuse imagery:
Web giants Google, Facebook and Twitter have joined forces with a British charity in a bid to remove millions of indecent child images from the net. In a UK first, anti-abuse organisation Internet Watch Foundation (IWF) has begun sharing lists of indecent images, identified by unique "hash" codes. Wider use of the photo-tagging system could be a "game changer" in the fight against paedophiles, the charity said. Internet security experts said images on the "darknet" would not be detected.
The IWF, which works to take down indecent images of children, allocates to each picture it finds a "hash" - a unique code, sometimes referred to as a digital finger-print. By sharing "hash lists" of indecent pictures of children, Google, Facebook and Twitter will be able to stop those images from being uploaded to their sites.

On the contrary; see the links in the post above yours. This is guaranteed to be abused. Indeed, the only reasonable conclusion is that the whole intention of the list is to be abusive.
Blocking entire websites is a lot more useful to censors than blocking specific images. That makes the one list that all those links reference much more attractive to abusers than this list.

And yet it could still be useful. This just adds another tool into their censorship toolkit.
