Diploma-mill owners are an elusive bunch. They flood e-mail boxes with offers of cheap college degrees, and collect payment through Web sites, then filter that money into overseas bank accounts. When the police try to shut one of the businesses down, the owners just set up shop elsewhere, often in a poor country with weak fraud laws. Unable to snuff out these illegal businesses, many states have changed their strategy: if you can't catch the dealers, go after the consumers. A handful, like Illinois, Indiana, and New Jersey, have recently criminalized the use of fake degrees.

In the US, the government is not directly implemented in the procedure of accreditation. Private agencies are taking care of this. The Education Department is recognizing some agencies. However, they do not do much to stop the activities from less honest ones. Several education institutes are not accredited due to the high procedure costs.
