The Bing news is part of a larger story from the Times about how various tech companies are dealing with child porn on their platforms.
The Times criticizes a tech industry which they say is looking the other way: Amazon, whose cloud storage services handle millions of uploads and downloads every second, does not even look for the imagery. Apple does not scan its cloud storage, according to federal authorities, and encrypts its messaging app, making detection virtually impossible. Dropbox, Google and Microsoft’s consumer products scan for illegal images, but only when someone shares them, not when they are uploaded. And other companies, including Snapchat and Yahoo, look for photos but not videos, even though illicit video content has been exploding for years. (When asked about its video scanning, a Dropbox spokeswoman in July said it was not a “top priority.” On Thursday, the company said it had begun scanning some videos last month.)
The largest social network in the world, Facebook, thoroughly scans its platforms, accounting for over 90 percent of the imagery flagged by tech companies last year, but the company is not using all available databases to detect the material. And Facebook has announced that the main source of the imagery, Facebook Messenger, will eventually be encrypted, vastly limiting detection.
