They're addicted.
Addicted to the brain drilling algorithm.
Addicted to their influence.
Addicted to believing 10s of thousands or 100s of thousands or millions of followers love them.
It's sad, really sad.
Respect for Stephen Fry who simply left an image of GOODBYE in Scrabble tiles and deleted an account with 12.5 million followers. He broke the addiction. Now happily gaining new followers.
