Facebook CEO Mark Zuckerberg has vowed to "fix" Facebook, in what he described as his personal challenge for 2018.
In a post on his page on the social network, he said it was making too many errors enforcing policies and preventing misuse of its tools.
Mr Zuckerberg has famously set himself challenges every year since Facebook started in 2009.
Social media firms have come under fire for allowing so-called fake news ahead of US and other elections to spread.
Facebook in particular has been criticised for allowing Russia-linked political ads in the run-up to the 2016 US presidential vote.
Mr Zuckerberg said he intended to focus on "important issues", which he listed as "protecting our community from abuse and hate, defending against interference by nation states, or making sure that time spent on Facebook is time well spent".
"We won't prevent all mistakes or abuse, but we currently make too many errors enforcing our policies and preventing misuse of our tools," he wrote.
"If we're successful this year then we'll end 2018 on a much better trajectory."
