Up to 2.7M Europeans affected by Facebook data breach, EU says

Facebook managed to delete private messages from people's inboxes that were sent by CEO Mark Zuckerberg.

Denham said Facebook had been co-operating with the investigation and she was "pleased" with changes they have made. These included limited the retention period for Marks messages in Messenger. And until this feature is ready, we will no longer be deleting any executives' messages.

In the future, you'll be able to delete your messages from other peoples' inboxes.

Had Facebook performed an audit at the time, it could have likely prevented the entire scandal - which has undercut users' trust in the company. However, to control the damage already done, Facebook has said that it will roll out an "Unsend" feature for all Messenger users in the coming months.

The move also comes amid concerns that Russian-sponsored entities delivered Facebook ads designed to create discord and confusion ahead of the election and that firms like Cambridge Analytica created messages based on psychographic profiles gleaned from the platform to influence voters.

EU spokesman Christian Wigand said EU Justice Commissioner Vera Jourova will have a telephone call with Facebook COO Sheryl Sandberg early next week to address the massive data leaks. Tellingly, the replies to the messages sent by Zuckerberg remained in the chat logs, preserving a one-sided history of a two-sided conversation. In an emailed statement to Wccftech, the company promised that it won't allow Zuckerberg or other executives to use this feature anymore until it is launched for everyone else, as well.

In Canada, we've been testing a new feature called view ads that lets you see the ads a Page is running - even if they are not in your News Feed.

Most people understand that when sending a text message, through Messenger or pretty much any other messaging service, it stays out there until when and if the recipient decides to delete it.

Deleting messages quietly, and selectively, also appears to fly in the face of Facebook's campaign to "make the world more open and transparent". "This may take some time", a Facebook spokeswoman wrote in an email on Friday. "We should have done this sooner - and we're sorry that we did not". CNBC reported on Thursday that Facebook sent a physician on a secret mission to ask hospitals to anonymously share patient data.

The reason behind using this feature was to delete embarrassing messages from going viral around.

The tool was discovered by TechCrunch, which noticed a discrepancy between emailed receipts of Facebook messages being received (which Facebook can not retract) and the actual contents of Facebook inboxes.
