Information brokers that market data sources to the investigation community are concerned with our opinions of their service and the accuracy of the information they provide to us. We are their clients. Word of mouth in this specialized community can make or break them. The major players in the cottage industry of information brokerage cater to investigators, law enforcement, attorneys, and businesses with a legal purpose. They do not sell information to the general public.
Good companies have ethical standards and are concerned with liability.
When the public orders a report from an info broker over the Internet - they are a customer. There is no ongoing relationship. The information is generally inferior. To most info brokers that sell direct to the public your credit card is more important than your satisfaction. Investigators utilize these types of services again and again.
