This is an interesting little service: https://www.twitteraudit.com https://www.twitteraudit.com "takes a random sample of 5000 Twitter followers for a user and calculates a score for each follower. This score is based on number of tweets, date of the last tweet, and ratio of followers to friends. We use these scores to determine whether any given user is real or fake. Of course, this scoring method is not perfect" It says that, as of 4 years ago, 28% of Paul Graham's followers were fake and 30% of Elon Musk's were fake.
