Facebook disabled 583 million fake accounts in the first three months of this year, one of the company's executives confirmed in a blog post on Tuesday.
Guy Rosen, VP of product management, said the social media giant blocks millions of daily attempts to create fake accounts from being registered.
The company estimates around 3 to 4 percent of the active Facebook accounts on the site during the first three months of 2018 were fakes, Mr Rosen said.

The numbers were released in Facebook's Community Standards Enforcement Report, which covers areas including fake accounts, spam, hate speech, graphic violence, terrorist propaganda, and nudity.
"We took down 21 million pieces of adult nudity and sexual activity in Q1 2018 - 96 percent of which was found and flagged by our technology before it was reported," said Mr Rosen.
"Overall, we estimate that out of every 10,000 pieces of content viewed on Facebook, seven to nine views were of content that violated our adult nudity and pornography standards."
For graphic violence, Facebook took down or applied warning labels to about 3.5 million pieces of violent content during the period - 86 percent of which was identified by Facebook technology before it was reported.
For hate speech, Mr Rosen said Facebook's technology "still doesn't work that well and so it needs to be checked by our review teams".
He said the company removed 2.5 million pieces of hate speech in Q1 2018 - 38 percent of which was flagged by Facebook.
"We believe that increased transparency tends to lead to increased accountability and responsibility over time, and publishing this information will push us to improve more quickly too," Mr Rosen said.
He said the company is investing "heavily" in technologies such as artificial intelligence to assist in preventing online abuse an area he admits Facebook still has "a lot of work to do" to improve.
