Beyond the "aging reset" problem, there's an even more dangerous backfire scenario: creditors correcting errors that were actually in YOUR favor. This is the trap most people never see coming.
Creditors don't always report perfectly. Sometimes they make mistakes that actually BENEFIT you - and you may not even know it. These silent gifts can be brutally taken away the moment you file a dispute.
During investigation, the creditor pulls your full account history and realizes: "Wait, we were actually being too lenient in our reporting." They are then legally REQUIRED to correct their records - against you.
These "errors in your favor" are fragile. Any investigation triggers a full audit that can expose the truth and devastate your score.
