The fake warning is being spread due to its chain mail format with the message encouraging those who receive it to pass it on to more users.
It reads: “Hi....I actually got another friend request from you yesterday...which I ignored so you may want to check your account.
“Hold your finger on the message until the forward button appears... then hit forward and all the people you want to forward too....I had to do the people individually. Good Luck!”
This indicates that the recipient could be a victim of some sort of cloning scam where people steal an identity on Facebook.
By doing so, scammers can add the user’s friends and potentially garner personal information on the person whose identity they have assumed.
Facebook, however, is reported to have stated that this current message is not linked to a genuine issue.
An official for the site, speaking to the Daily Mail, said they were aware of the notice being spread.
They were not aware of a virus attached to it nor an increase in reports of account impersonation.
Advice has been to simply delete the message if sent it and if there are genuine cloning concerns to check for an actual duplicate account.
The Standard has contacted Facebook for comment.
Many have expressed dismay at their inbox being filled with people sending the warning.
One, writing on Twitter, said: “Stop sending me warnings about Facebook Cloned Accounts.
That in itself is a HOAX. You're flooding my inbox for nothing..... If you annoy me I will unfriend you and THEN the friend request will be for real...”
Others described it as “irritating” while one said people sending it on were “gullible”.
The hoax comes days after Facebook announced that millions of accounts on its site had been targeted in a data breach.
Hackers exploited an issue with the social media platform’s “view as” feature with “access tokens” being stolen, which can give temporary access to an account.
Facebook has said it has addressed this issue by resetting tokens and is continuing to investigate the situation.
