For example, it could scan social media and use that information to send a very large number of people very personalized messages that manipulate them into doing X. Here, X may include meeting other people to tempt/coerce them into doing Y. The reason this isn't possible now is that nobody has the time to look at millions of social media profiles and then write millions of personalized messages. To do it, you would need a lot of people who you would have to convince, including paying them. And even so, things like doomsday cults and terrorist organizations already exist.
