Over 583 Facebook accounts have on Tuesda being shut-down in the first three months of the year, 2018.
According to Facebook, the accounts came on top of blocking millions of attempts to create fake accounts daily.
It claimed to detect almost 100 percent of spam and to have removed 837 million posts assimilated to spam over the same period.
Facebook pulled or slapped warnings on nearly 30 million posts containing sexual or violent images, terrorist propaganda or hate speech during the first quarter.
Improved technology using artificial intelligence had helped it act on 3.4 million posts containing graphic violence, nearly three times more than it had in the last quarter of 2017.
In 85.6 percent of the cases, Facebook detected the images before being alerted to them by users, said the report, issued the day after the company said about 200 apps had been suspended on its platform as part of an investigation into misuse of private user data.
The figure represents between 0.22 and 0.27 percent of the total content viewed by Facebook’s more than two billion users from January through March.
“In other words, of every 10,000 content views, an estimate of 22 to 27 contained graphic violence,” the report said.
Responses to rule violations include removing content, adding warnings to content that may be disturbing to some users while not violating Facebook standards; and notifying law enforcement in case of a “specific, imminent and credible threat to human life”.
