But as the others have indicated, it is yet fairly simple to get a Facebook users' phone number through other means, like public groups, many of which were made when someone lost their phone or upgraded to a new one and required to gather the numbers of their family and friends. Until the Unsend feature is released for everyone, Facebook says it won't unsend or retract any more of Zuckerberg's messages. And people using our secret message feature in the encrypted version of Messenger have the ability to set a timer - and have their messages automatically deleted.
Cambridge Analytica tweeted on Wednesday, "When Facebook contacted us to let us know the data had been improperly obtained, we immediately deleted the raw data from our file server, and began the process of searching for and removing any of its derivatives in our system".
In the wake of Cambridge Analytica scandal, Facebook has been making rigorous efforts for remediation of the breach of user trust caused by the scandal. "This may take some time", a Facebook spokeswoman wrote in an email on Friday. And until this feature is ready, we will no longer be deleting any executives' messages.
"In light of recent reports that AggregateIQ may be affiliated with SCL and may, as a result, have improperly received FB user data, we have added them to the list of entities we have suspended from our platform while we investigate", Facebook said in a statement.
TechCrunch notes that it has six sources that confirmed messages they received from Zuckerberg had been deleted from their inboxes. These included limiting the retention period for Mark's messages in Messenger.
The report said that old messages from before 2014 still appear to some users, indicating the retraction did not apply to all chats the CEO sent.
Facebook's terms of service don't give the right to remove content from users' accounts unless it violates the company's community standards.
Recently, in a blog post, Facebook Chief Technology Officer Mike Schroepfer, gave country-specific break-up of people affected by the data breach, saying information of up to 87 million people, mostly in the United States, may have been "improperly" shared with Cambridge Analytica via a quiz app, "thisisyourdigitallife", between November 2013 and December 2015.
