The BBC and Twitter moved quickly yesterday to remove a fake account impersonating the corporation's Breaking News Twitter page, but not before it had managed to spread an untrue story about the health of UK Prime Minister Boris Johnson.
The fake post was picked up by a prominent TV channel in Pakistan, which it aired for a short while as a news flash.
It subsequently aired an apology after realising its error.
It's not the first time that fake BBC accounts have appeared on Twitter during the Covid-19 crisis, and they have been deleted almost immediately.
So-called "imposter content" is a headache for news organisations because they spread misleading news while damaging their reputations.
While most cases appear to be trolling or mischief-making, some fake accounts are attempts to direct readers to their own websites for financial gain.
