This site believes sharing credit card information and other 'private' data is ok. I did a facebook ad campaign about a year ago, and forgot I had entered my credit card information to pay for this service. It was NOT until my son used a gaming site, and hit the 'buy' credit button that I remembered. Yup, $100 later I learned a hard lesson. I sent several emails to facebook, as well as my local TV station did, searching for answers and some logic as to why this happened. Well, 2 months have gone by and NO response. Lesson learned, if it is on facebook they consider it public and sharable with whomever they choose, regardless of what information it is... Users be aware...
