I literally only still have my FB account until I can sell all of the stuff I have listed on marketplace. Every other aspect of my FB account was deleted years ago. At first I kept the account because of the broken promise of never requiring a FB account for the Quest. They finally changed that(sort of, they require a meta account instead), but I still kept the account for marketplace. It’s the only place I’ve been able to successfully sell anything for at least 3 or 4 years. Once I sell off the last few items I have listed there(really need the money at the moment), I can finally delete my account fully.
