Facebook homepage showing celebrity pages
On Twitter, it appears that users are all seeing the same problem: the homepage is not showing posts from friends, but instead seemingly random posts on celebrity pages.
One user wrote: “@facebook is down or what???? My feed is spammed with what random people are commenting on celebrity pages”
Another shared: “Anyone else #Facebook feed being weird, randoms posting to celebs?”
Has Facebook been hacked?
Facebook has not confirmed any outage or issue with the website at the time of writing, and there is no evidence to suggest Facebook has been hacked.
Keen Facebook users have been using the bug to say hello to the wider Facebook community.
One shared on Adele’s Facebook page, “I don’t know but I want to try it too, hello!”
While another wrote: “Hey mama I’m famous.”
According to the Twitter reports, the issue appears to be affecting people across the world as well as showing various celebrity Facebook pages.
