“When terrorists misuse the internet,” Facebook explained in a blog post on Wednesday, July 24, “they often upload the same piece of content to multiple platforms to maximize their reach.” This has allowed the social media giant—along with Google, Microsoft and Twitter under the Global Internet Forum to Counter Terrorism (GIFCT) alliance—to “more quickly identify and take action against potential terrorist content on our respective platforms.”
In 2018, the alliance reached its intended milestone of assembling 100,000 such hashes. In the first half of 2019, though, the number has already doubled. There are now “more than 200,000 unique hashes in the database,” each of which is described as a digital fingerprint pointing to a known piece of terrorist content.
The scale speaks for itself, as does news from the frontline.
