A tipline was set up 26 years ago to combat online child abuse A new report from the Stanford Internet Observatory finds that it has not lived up to its potential and that technological and other improvements are needed to help law enforcement take action against abusers and protect victims.
Solutions to what the researchers describe as an “extremely valuable” service also need to be urgent as new artificial intelligence technologies are at risk. its problems worsened,

“Almost certainly in the years to come, cyber tiplines will be overwhelmed Realistic looking AI content“That will make it even more difficult for law enforcement to identify actual children who need to be rescued,” said researcher Shelby Grossman, author of the report.
The service was established by Congress as the main line of defense for children who are exploited online. By law, tech companies must report any child sexual exploitation material found on their platforms to the system, which is run by the National Center for Missing and Exploited Children. After receiving a report, NCMEC attempts to locate those who sent or received the material – as well as the victims, if possible. These reports are then sent to law enforcement.

While the sheer volume of Cyber Tipline reports is overwhelming law enforcement, researchers say the volume is just one of many problems with the system. For example, many reports sent by tech companies such as Google, Amazon and Meta lack important details, such as sufficient information about the identity of an offender, the report said. This makes it difficult for law enforcement to know which reports to prioritize.
Alex Stamos, using the initials for child sexual abuse material, said, “There are significant issues throughout the system right now and these cracks are going to become chasms in a world where AI is generating brand new CSAM.” Stamos is a Stanford lecturer and cybersecurity expert.
The system lags behind technologically and suffers from a persistent challenge among government and non-profit tech platforms: a shortage of highly skilled engineers, who can earn far higher salaries than those in the tech industry. Sometimes those employees are also poached by the same companies who send reports.

Then there are legal hurdles too. According to reports, court decisions have stopped NCMEC staff from examining certain files (for example, if they are not publicly available) before turning them over to law enforcement. Many law enforcement officials believe they need a search warrant to access such images, slowing down the process. Sometimes, multiple warrants or subpoenas are required to identify the same criminal.
It is also easy to distract the system. Reports show that NCMEC recently achieved the milestone of one million reports in a single day due to a meme that was spreading across multiple platforms – which some people thought was funny and others shared out of outrage. Was doing.
“That day really inspired them to make some changes,” Stamos said. “It took them several weeks to clear that backlog” by making it easier to collect those images together.
Cyber Tipline received more than 36 million reports in 2023, almost all of which were from online platforms. Facebook, Instagram and Google were the companies that sent the highest number of reports. The total number is increasing dramatically.
About half of the tips sent last year were actionable, meaning NCMEC and law enforcement can follow up.
Hundreds of reports were related to the same perpetrator, and many included multiple images or videos. Nearly 92% of reports filed in 2023 involved countries outside the US, a big change from 2008 when most involved victims or perpetrators inside the US
There are some false alarms. “It’s crazy when law enforcement gets reports that they think are definitely adults,” Grossman told reporters. “But the system encourages platforms to be very conservative or report potentially borderline content, because if it’s found to be CSAM and they knew about it and didn’t report it, they could get a fine. “
A relatively simple solution proposed in the report would be to improve how tech platforms label what they are reporting to differentiate between widely shared memes and something that deserves closer scrutiny.
Stanford researchers interviewed 66 people involved with the Cyber Tipline, ranging from law enforcement to NCMEC employees to online platform employees.
NCMEC said it looked forward to “exploring recommendations internally and with key stakeholders”.
“Over the past few years, the complexity of the reports and the seriousness of crimes against children have continued to evolve. Therefore, leveraging emerging technological solutions throughout the cyber tipline process protects more children and holds perpetrators accountable,” a statement said.
Among other findings of the report:
– The Cyber Tipline reporting form does not have a dedicated field to submit chat-related content, such as sextortion messaging. The FBI recently warned “Huge increase” in sextortion. Cases targeting children – including financial sexual exploitation, where someone threatens to release incriminating photographs unless the victim pays up.
– Police detectives told Stanford researchers that they are having difficulty convincing their superiors to make these crimes a priority, even when they submit detailed written descriptions to emphasize their seriousness. “They get nervous when they read it and they don’t really want to think about it,” Grossman said.
– Several law enforcement officials said they were not able to fully investigate all reports due to time and resource constraints. A single detective may be responsible for up to 2,000 reports per year.
– Outside the United States, especially in poorer countries, the challenges with reporting child abuse are particularly severe. Law enforcement agencies may not even have reliable Internet connections, “decent computers” or gas for cars to execute search warrants.
– Pending legislation passed by the U.S. Senate in December would require online platforms to report child sex trafficking and online solicitation to Cyber Tiplines and give law enforcement more time to investigate child sexual exploitation. Currently, the tipline does not provide direct ways to report suspected sex trafficking.
While some advocates have proposed more intrusive surveillance laws to catch abusers, Stamos, the former chief security officer of Facebook and Yahoo, said they should try simpler solutions first.
“There is no need to violate users’ privacy if you want to put more pedophiles in jail. They’re just sitting there,” Stamos said. “The system doesn’t work very well at taking the information that currently exists and then turning it into a prosecution.”
