Can you post a citation here?

Googling, all I can find are references to a database of consumer complaints that people have proactively made to the agency about Credit Card companies being abusive.

That work seems like good digital government at it's best to me -- helping aggregate and track down fraudulent and abusive companies before they hurt more people through voluntarily submitted complaints from consumers.

That db is here: http://www.consumerfinance.gov/complaintdatabase/

They even have a REST API and visualizations.
