Keep your friends close, but keep your personal information even closer. What you do and say and even who you interact with online, especially on social sites like Facebook, can and will affect your credit rating sooner or later. Banks are using your own information against you by gathering data they can’t legally obtain from applications. Bankers may soon join lawyers and politicians on the most despised profession list if this trend continues.
In other words: choose your online friends wisely, for they may one day determine your APR.
