Bad Idea: Company claims to know credit score from Twitter friends

According to a data mining company, the old adage of being judged by the friends you keep translates easily into the digital friends you keep.

Rapleaf, a social media monitoring company, claims that by analyzing public information such as the friends you have on Twitter it can assess how creditworthy you are and how likely you are to respond to advertising.

Rapleaf monitors public digital conversations and stores away your Twitter and Facebook status updates, restaurant reviews, Amazon book reviews and plenty of other online public information in its database of 378 million profiles to profile you.
