King, 72, was a big user of Facebook, but deactivated his account on Friday.
In a weird, 21st century twist, King took to another social media platform, Twitter, to announce his departure.
“I’m quitting Facebook. Not comfortable with the flood of false information that’s allowed in its political advertising, nor am I confident in its ability to protect its users’ privacy. Follow me (and Molly, aka The Thing of Evil) on Twitter, if you like,” King wrote to his 5.6 million followers.
King, the author of “The Shining” and numerous other horror novels, was reacting to Facebook’s refusal to ban paid political ads. Facebook has also refused to fact-check political ads, which has also prompted others to leave the site.
