Washington: Facebook said a bug in a system designed to detect fake profiles had disabled a number of legitimate accounts on the social network.
Facebook did not say how many accounts were disabled by the bug, which primarily affected women`s accounts, according to technology blogs.
"Earlier today, we discovered a bug in a system designed to detect and disable likely fake accounts," a Facebook spokesman said on Tuesday.
"The bug, which was live for a short period of time, caused a very small percentage of Facebook accounts to be mistakenly disabled," the spokesman said in a statement.
"Upon discovering the bug, we immediately worked to resolve it," he said. "It`s now been fixed, and we`re in the process of reactivating and notifying the people who were affected."
Facebook has more than 500 million members around the world.
