The Wall Street Journal said the FBI is currently planning to actively collect data from social platforms such as Twitter, Instagram, and Facebook, which also seem to conflict with their privacy policies. In particular, Facebook, as part of an agreement with the Federal Trade Commission, must comply with restrictions that relate to the way it collects and processes user data.
From the wording of the request, the agency only seeks to collect publicly available data and intends to collect such data while respecting civil liberties and privacy protection. The FBI says it will collect names, pictures, and IDs from public archives and combine them with information from other sources and algorithms that tag specific keywords in social interactions.
Large technology platforms have a lot of user data, and artificial intelligence tools can filter faster than humans, but algorithmic threat detection can lead to a lot of false positives. The FBI says the alerts will be handled by a dedicated team of people.
