I'm very skeptical about debt cancellation because if there was a way to make it into a business, it'd be a business. The people who talk about doing that all lose money as a charity, or they're sovereign citizens who think they found some tax loophole.
The credit bureau thing is funny because again, ethically you should but once you do you open yourself up to a LOT more liability. So most agencies won't unless it's an in-house agency for CapitalOne or something.
You as the consumer should always dispute everything on your credit report every so often.
Q1: As an insider, how feasible is that strategy? Q2: As the collector do you report to credit bureaus that it's cleared? does it have a meaningful impact on debtors' credit?
