I've been the victim of the identity fraud, a fraud prevention company called me up in the summer of 2006 stating that all my key personal info had shown up on an Eastern Russia Hacker site -- I got Fraud Alerts on my CBRs, filed a police report and
What KILLED me was that there was income earned in my name, under my social security number, and it caused some IRS troubles that turned in a lien.
The disputing process from a fraud case can be successfully overcome by submitting the proper police reports and supporting documentation to all the OCs and get them to start to removal process with the CAs. This will have a ripple effect to the CRAs, if you have the proper police reports, sworn affidavits and denial of liability letters, you should be in good shape.
It might take 3 to 6 months though, but to get those derogs off with their 7 year sticking power is what you're after.
