Every time someone in the UK searched for child abuse material on Pornhub, a chatbot appeared and told them how to get help.
A trial program conducted by Pornhub in collaboration with UK-based child protection organizations aimed to deter users from searching for child abuse material (CSAM) on its website. Whenever CSAM-related terms were searched, a warning message and a chatbot appeared, directing users to support services. The trial reported a significant reduction in CSAM searches and an increase in users seeking help. Despite some limitations in data and complexity, the chatbot showed promise in deterring illegal behavior online. While the trial has ended, the chatbot and warnings remain active on Pornhub's UK site, with hopes for similar measures across other platforms to create a safer internet environment.
4.4 million sounds a bit excessive. Facebook marketplace intercepted my search for "unwanted gift" once and insisted I seek help. These things have a lot of false positives.
Not necessarily trafficking, but could be trafficking-adjacent.
There used to be "child rehoming" 'services' on Facebook and the like, for people who regret adopting a kid, and pass them to others. Here's a fairly in-depth article on the whole affair. Unsurprisingly, it didn't go well.
EDIT: In hindsight, "unwanted gift" could also be about people getting unexpectedly pregnant, and putting the resulting child up for adoption, but not wanting to go through legal means for one reason or another, which seems a more likely answer.
Do you really think human traffickers are listing people under secret codes on accounts obviously linked to their real identity with their real face? Remember the ikea thing where vendors who didn't specify a price received an absurd default price for their goods eg 9999.99 and people that furniture that was listed at that price corresponded to kids being sold?
