In the reports, Facebook revealed hundreds of millions of accounts were fake as it published content removal numbers for the first time.
The company removed 583 million fake accounts, although these were not all active at the same time.
The figures show how much graphic violence, adult nudity and sexual activity, terrorist propaganda, hate speech, spam, and fake accounts that are uploaded to its platform.
The company stated that between October 2017 and March 2018 it took down or put warning labels on:
– 837 million pieces of spam
– 583 million fake accounts
– 21 million pieces of adult nudity and sexual activity
– 3.5 million pieces of violent content
– 2.5 million pieces of hate speech
Explaining the figures, the company’s vice president of product management Guy Rosen said:
“It’s important to stress that this is very much a work in progress and we will likely change our methodology as we learn more about what’s important and what works.”
The high numbers of spam that the company reported were caught by Facebook’s internal tools, the company said and relied on taking down the fake accounts which spread it.
Many of these accounts were “disabled within minutes of registration” according to the company, although it provided only surface-level figures on the total number of accounts banned.
Mr Rosen added: “We believe that increased transparency tends to lead to increased accountability and responsibility over-time, and publishing this information will push us to improve more quickly too.
“This is the same data we use to measure our progress internally – and you can now see it to judge our progress for yourselves. We look forward to your feedback.”
Such feedback will be on the way from the House of Commons, where an inquiry has again criticised Facebook for failing to answer its questions about how the company handles UK citizens’ data.
