When it comes to social media sites (and particularly those that involve photo-sharing), you might want to also account for 1) the people who are forced to spend all day every day with politicians, attorneys general, and policy makers in every state and every country; 2) the hundreds of people who sit and sift through photographs/video looking for illegal content; 3) the round-the-clock staff who field calls from FBI and police; 4) the large teams who battle spam, phishing and hacking; 5) the legal team who has to deal with everyone and then some suing them over issues of safety, porn, etc.
