There are a lot of ways to monetize it. Run 2FA attacks on celebrity accounts' phone numbers, dox anon accounts that post racist stuff or follow gay porn and blackmail them, etc etc.
You could threaten to call up a random person's employer and call them a racist unless they paid you. Seems as likely to work as this would be.
You would need someone high profile enough to get the attention of a social media mob to really threaten people.
