I think you hit the nail on the head. These celebrities are not on Facebook. Most of the accounts we see are not them. They have firms and people who manage it for them, avoiding scandle and making sure every word is meticulously crafted. None of it is authentic.

Asking them to leave Facebook is basically asking them to uncheck Facebook from a social media manager's management platform. It's a non thing to them. The celebrity isn't on their phone posting things, it's all corporate now.

The most macklemore may have done was write the baseline to his statement, but a team of PR people smoothed and rewrote it. He then probably gave a thumbs up to it afterwards. If there's anything I'm 100% sure of, the words we read were not typed out by him.
