Facebook searches is due to its larger, more diverse photo selection compared to the FBI's closed database. Mark Zuckerberg showed no worries when speaking about Facebook's AIs, saying, "Unsupervised learning is a long-term focus of our AI research team at Facebook, and it remains an important challenge for the whole AI research community" and "It will save lives by diagnosing diseases and driving us around more safely.

Facebook also has its own built-in messaging system that people can send messages to any other user, unless they have disabled the feature to "from friends only". Stalking is not only limited to SNS stalking, but can lead to further "in-person" stalking because nearly 25% of real-life stalking victims reported it started with online instant messaging (e.g., Facebook chat).
