SAN FRANCISCO (Reuters) – Facebook Inc said on Wednesday that company moderators during the last quarter removed 8.7 million user images of child nudity with the help of previously undisclosed software that automatically flags such photos.

The machine learning tool rolled out over the last year identifies images that contain both nudity and a child, allowing increased enforcement of Facebook’s ban on photos that show minors in a sexualized context.

A similar system also disclosed on Wednesday catches users engaged in “grooming,” or befriending minors for sexual exploitation.

Facebook’s global head of safety Antigone Davis told Reuters in an interview that the “machine helps us prioritize” and “more efficiently queue” problematic content for the company’s trained team of reviewers.

The company is exploring applying the same technology to its Instagram app.

Under pressure from regulators and lawmakers, Facebook has vowed to speed up removal of extremist and illicit material. Machine learning programs that sift through the billions of pieces of content users post each day are essential to its plan.

Machine learning is imperfect, and news agencies and advertisers are among those that have complained this year about Facebook’s automated systems wrongly blocking their posts.

Davis said the child safety systems would make mistakes but users could appeal.

“We’d rather err on the side of caution with children,” she said.

Facebook’s rules for years have banned even family photos of lightly clothed children uploaded with “good intentions,” concerned about how others might abuse such images.

Before the new software, Facebook relied on users or its adult nudity filters to catch child images. A separate system blocks child pornography that has previously been reported to authorities.

Facebook has not previously disclosed data on child nudity removals, though some would have been counted among the 21 million posts and comments it removed in the first quarter for sexual activity and adult nudity.

Shares of Facebook fell 5 percent on Wednesday.

Facebook said the program, which learned from its collection of nude adult photos and clothed children photos, has led to more removals. It makes exceptions for art and history, such as the Pulitzer Prize-winning photo of a naked girl fleeing a Vietnam War napalm attack.

The child grooming system evaluates factors such as how many people have blocked a particular user and whether that user quickly attempts to contact many children, Davis said.

Michelle DeLaune, chief operating officer at the National Center for Missing and Exploited Children (NCMEC), said the organization expects to receive about 16 million child porn tips worldwide this year from Facebook and other tech companies, up from 10 million last year.

With the increase, NCMEC said it is working with Facebook to develop software to decide which tips to assess first.

Still, DeLaune acknowledged that a crucial blind spot is encrypted chat apps and secretive “dark web” sites where much of new child pornography originates.

Encryption of messages on Facebook-owned WhatsApp, for example, prevents machine learning from analyzing them.

DeLaune said NCMEC would educate tech companies and “hope they use creativity” to address the issue.

Russia buries victims of mall blaze as flags fly at half mast

KEMEROVO/MOSCOW (Reuters) – Funerals began in Russia on Wednesday for the 64 people, most of them children, whose deaths in a fire at a Siberian shopping mall have roused public anger over official corruption and incompetence.

Flags on government buildings across Russia flew at half mast, state TV and radio stations removed light entertainment shows from their schedules, and lawmakers in Moscow observed a minute of silence.

The fire at the Winter Cherry mall in the city of Kemerovo on Sunday killed 41 children. Investigators have not confirmed the cause of the fire, but the high death toll has been blamed on reported shortcomings in the mall’s safety procedures.

At a funeral service in an Orthodox church in Kemerovo, about 3,600 km (2,200 miles) east of Moscow, women wailed as prayers were sung over three coffins, including two small caskets for children.

Sergei and Natalia Agarkov buried two school-age children, Konstantin and Maria. The children’s grandmother, Nadezhda Agarkova, was also killed.

All three had gone to see a film at a cinema on the top floor of the shopping center and had been unable to get out of the auditorium when the fire broke out. Russian media reported the doors had been locked.

“This tragedy is made even worse by the fact that children became victims of the blaze. Great grief is upon all of us and there are no words that would express our common pain,” the priest told the mourners, who held candles and repeatedly crossed themselves.

President Vladimir Putin, visiting the disaster scene on Tuesday, promised angry residents that those responsible for what he called criminal negligence would be punished and declared Wednesday a national day of mourning.

Putin on Wednesday ordered similar shopping centers across Russia to be inspected to make sure they were well prepared in the event of a fire.

Some victims’ relatives say they believe a cover-up is under way and that the death toll is higher than 64, something Putin has denied. Investigators on Wednesday said they had opened a criminal case into a Ukrainian prankster who they said had spread disinformation about the death toll.

ANTI-GOVERNMENT PROTEST

Investigators say their main theory is that an electrical short circuit caused the fire.

Almost all the bodies have been recovered, many of which could be identified only via DNA testing. A further 14 people remain in hospital.

Russia has rigorous fire safety rules and a system of regular inspections, but these efforts are undermined by endemic corruption which affects many aspects of life in the country of 144 million people.

Moscow reduced the number of inspections for certain businesses after complaints that inspectors were extorting bribes in exchange for turning a blind eye to violations.

But some business owners in Kemerovo said this meant that safety shortcomings were not being identified.

The governor of the region where the fire took place, Aman Tuleyev, sacked two senior officials on Wednesday, the RIA news agency reported.

Investigators have also detained and charged five people over the fire, including a security guard who they accuse of turning off the public address system and the mall’s manager who is accused of violating fire safety regulations.

At least one vigil held in memory of the dead in cities across Russia has turned into an anti-government demonstration.

At a Moscow gathering on Tuesday attended by several thousand people, including opposition leader Alexei Navalny, protesters held banners reading “Bribes kill children” and “We demand a real investigation”.

Some chanted “Putin – resign!”, ten days after Putin secured a comfortable election win for another six-year term in office.
