TRUSTe did a bang up job establishing themselves as the must have credential that sites paid them well for. You offer eye candy and a pretty little logo to provide a sense of security.

Many victims don't realize there's a problem until years later, when they are turned down because of the poor credit history someone else racked up in their name.
