Facebook is starting to test a new option: through comments from strangers on public posts, users will see information that matches their profile.
For example, on the commentator's name it may appear that he is in the same city, working in the same company or in the same group on social networks. Testing is still taking place in the US Facebook segment. Such an innovation could cause new discussions about the security of information that social networks know about users. At the same time, Facebook reported that during the test, only information that users publicized on their site will be displayed.
