Zuckerberg's refusal to answer questions has not helped his company's image either.
Facebook Chief Executive Officer Mark Zuckerberg has announced a crackdown on who buys ads about divisive issues, saying this month that the company would require every such advertiser to confirm their identity and location.
Facebook released a blog post detailing how the service collects information about its users from the web.
"My directives to my line agencies is to provide me with a brief covering both the advantages and disadvantages of use of Facebook, the vulnerabilities that includes not just the protection of personal data, but wider social issues like security and safety of users, the time-consumption and productivity of users - especially school-age children and employees, and of course the wider issue of cybersecurity and cybercrime".
Mark Zuckerberg was asked numerous times during his testimony before Congress whether additional apps had similarly mishandled user information. However, don't expect a way out. But there's absolutely no way to turn it off.More news: Milos Forman Dies At 86: Celebrities, Fans React To 'Amadeus' Director's Death

Whether it's information from apps and websites, or information you share with other people on Facebook, we want to put you in control - and be transparent about what information Facebook has and how it is used.
For instance, if you see "Like" and "Share" buttons on an app or site, that also gives Facebook information about you. To start with, your IP address (think of it as your address on the Internet), your browser, and your operating system are all shared with Facebook.
Many websites and apps use Facebook services to make their content and ads more engaging and relevant. While we don't know specifics about the newly revealed apps, Kaiser did highlight one in particular called "Sex Compass". "Period." Whenever someone says "period" like that, something feels off. Zuckerberg stuck to his response throughout the marathon hearing: that Facebook is conducting an audit on all apps that have access to large amounts of data. Finally, Facebook ads and measurement tools facilitate websites and apps with advertisements.
The researchers labeled suspicious ad-buyers as groups with pages that have been inactive, inaccessible, removed or banned by Facebook since the election and there was no information available publicly about them.
