Facebook's Terms of Service and Privacy Policy

For today's post, I'll be talking about one of the most popular social networking service Facebook, and how
they use your personal information and their action when there is a breach in security, which in this case, your Facebook account.

Firstly, your personal information that Facebook collects when you sign up with them and every time you interact or sharing information (photos, videos, comments, personal status, etc) on their website, do you ever wonder what exactly they doing with all that private information of yours? To answer that question, let me first tell you how Facebook makes money.

Facebook's Revenue

Facebook makes majority of its income in two ways advertising and collecting a fee from the app makers who use its Facebook Credit system. And to be successful at it, they need a lot of users to frequently interact the site, the more users Facebook has the higher the income.  

Information collected by Facebook

Facebook collects two types of information, personal details provided by user and usage data collected automatically as the user interact with the site.

Regarding personal information, there are a few pieces of data required to create a Facebook account, such as your name, gender and network. That information, along with your profile and cover photos, is publicly available and can not be changed other than deleting the account. Facebook may request permission to use user's email for notification purpose.

Facebook records website usage data, in terms of how users interact with each other and the site, commenting or sending a message, check-ins, Page likes, and other activity. Facebook then uses those data to improving the site or making marketing decisions(advertising), which allows advertisers to target their ads to the users.

Breach of Security

When it comes to breach of security, all Facebook does is to send the affected users a warning email stating that their personal information has been compromised, and then try to resolve the issue. You can read more about Facebook security by clicking on the link.

In the end, it all comes to protecting your personal information than what you can do after it's been compromised, because once it's happened it's too late and there isn't much you can do about it. So when it comes to using social network services (Facebook), only share information that is less private and you do not mind it been exposed to public, because we shouldn't fully trust any social network service.
