I think there are different levels of fakes. There are bots, which are complete ai and try to drive opinion and influence over, typically, political topics. Basically, they're computers doing propaganda for governments. That's about the fakest fake because it's not even a human. Then there are profiles that are 100% life, but human. Usually lie about their age, gender, and living situations and their stories are 100% fantasy and imagination, it's a complete fabrication of a life 100% different than their own. That's also incredibly fake. Then there are people who stretch the truth or change some details. Maybe add 4 inches to their height, and lie about their weight or wealth, but for the most part, their likes, dislikes, and stories are accurate to their feelings and happened mainly in that way.
