Facebook users around the world have reported issues with their homepage while trying to browse the app.
The problems are being highlighted on other social media platforms like Twitter, where people are flocking to post about seeing “random” people posting on the pages of celebrities.
Facebook owner Meta said it was aware of the reports and it was “working to get things back to normal”.
DownDetector, a website where people can log outages and issues with different platforms, started receiving reports of the glitch after 6am.
It received more than 2,500 reports from Facebook users about the feed, with some describing it as a “weird issue”.
“My feed is spammed with random people posting on celebrity pages?”, one Twitter user said.
Another wrote: “Hey @facebook, are you OK bro?”
Reports state that if someone has posted to a celebrity’s page, then everyone else following that famous individual will see the post come up in their newsfeed.
Such posts to popular pages are usually filtered out by an algorithm.
The unrelated messages are appearing above posts from friends and connections on the platform.
A spokesperson for Meta told Sky News: “We’re aware that some people are having trouble with their Facebook feed.
“We’re working to get things back to normal as quickly as possible and we apologise for any inconvenience.”
The issue seems to be affecting users across the globe, with outages reported in the UK, Spain, Canada, Mexico, Italy, France, the US, Poland, and Australia.
People have been trying to make the glitch work to their advantage by attempting to publicise their own interests or projects – such posts include requests for jobs, promotion of social channels and business adverts.
