No, they can't get around it.
Creditors are required to report the date of the first delinquency, also known as the FCRA Compliance Date, regardless of how many times it gets shuffled or sold. If they modify that date it is called re-aging and it is illegal.
Collection and charge-off accounts can be reported for up to 7 years and 6 months from the date you first fell behind on the account leading up to it being charged off or sent to collections. Here's an example:
January 1, 2001: You start missing your payments.
May 1, 2001: The account is charged off by the lender.
November 1, 2001: Account is sent to a collection agency.
June 29, 2008: Collection account and charge off must be removed from your credit reports.
The account can be reported for 7 1/2 years from January 1, 2001 – which happens on June 29, 2008. It doesn’t matter when the collection agency bought the account, and it doesn’t matter what date of last activity is listed on your credit report.
If you properly filed a dispute with the credit bureau and they didn't remove it from your report then you may have to file a complaint with the Federal Trade Commission. If the debtor is illegally reporting your date of delinquency on purpose then they could potentially be facing big violations.
