The underground marketplace for desirable social media handles (OG Handles) was explored in this excellent episode of Reply All: The Snapchat Thief [1].
In that story the basic technique was a SIM-swapping attack [2]. Fraudster calls the cell provider, claims to be the victim and that they lost their phone. Cell provider then ports the phone identity over to a new SIM. After that the fraudster just resets the account's password and gets the 2FA SMS (or even easier, one-time passwords) to their newly connected phone. Don't know if that same basic technique still applies nowadays, but in any case the most surprising part of the episode to me was how large and mature a black market there was for these account handles.
Read this as a fan of her work and a friend of several female geologists with stories from remote work camps. I was struck by the even-handedness of it.

He touches on this idea a lot, but most deeply in Infinite Jest where the parallels between between addiction to media and addiction to drugs is a major theme. In that story people have developed 'Entertainments,' basically video segments. Someone makes an Entertainment so unbelievably good that anyone who watches it is immediately stupefied and has no will to do anything but watch the Entertainment over and over. This Entertainment becomes a potent terrorist weapon since it can essentially take out anyone to whom it's broadcast.
