The case that gives the practice its regulatory record. In March 2020 the FTC settled charges against BoostMyScore, LLC, BMS, Inc. and their owner William O. Airy, in the U.S. District Court for the District of Colorado. The Commission's account of the marketing is worth reading in the defendants' own words, which the FTC quoted: "HOW TO HACK YOUR CREDIT SCORE. What is a tradeline? Steroids straight into the heart of your credit score. Adding a high quality 'tradeline' is the most effective way to quickly boost your credit score. Through a process called 'tradeline renting' or 'credit piggybacking,' you can overcome your credit woes."
The FTC alleged the defendants charged consumers "between $325 to $4,000, or even more," promised score increases "by anywhere from 100 to 120 points over two to six weeks," and could not substantiate those claims. It also alleged they coached the account holders selling authorized-user slots on how to keep their issuers from noticing, quoting call-center instructions on ending a call abruptly if a bank representative became "overly inquisitive."
What was actually charged, which is not what people assume. The complaint alleged violations of the FTC Act, the Credit Repair Organizations Act, and the Telemarketing Sales Rule. The CROA count is the one that does not depend on any view about piggybacking at all: charging consumers up front for credit repair services is unlawful regardless of whether the service works. The FTC's own summary of the lesson for marketers puts it plainly: "when offering credit repair services, asking for so much as one thin dime up front will land you in legal hot water."
The careful negative, which matters more than the case. The stipulated order prohibits the defendants from "selling fake access to another consumer's credit as an authorized user," from collecting advance fees for credit repair, and from "misrepresenting a product or service as being legal." That last prohibition is precise and is not a statement that the practice is illegal. It bars the defendants from telling consumers it is lawful. Reading the order as a holding that piggybacking is unlawful reads more into it than it says, and the distinction is the reason this remains a live business.
What the judgment tells a consumer about recovery. The order carried a monetary judgment of $6,630,678, partially suspended on payment of $64,863, on the basis of the defendants' inability to pay, with the full judgment immediately payable if they misrepresented their financial condition. The suspended-judgment structure is common in FTC consumer-protection settlements, and its practical meaning is that a judgment figure in a press release is not money returned to consumers.
Why the mechanism is unreliable even on its own terms. An authorized-user tradeline appears on the file, and how any particular scoring model treats an authorized-user account is a proprietary matter that neither the seller nor the buyer can verify. Two things follow that a purchaser cannot control. The account holder can remove the authorized user at any time, and the sellers in the FTC's case were paid for slots they rotated. And the issuer can close an account it believes is being used this way, which is what the coaching quoted by the FTC was designed to prevent.
What the industry says about it, attributed. Experian, on its own product marketing page for a competing service, writes that "Piggybacking services that add you to a stranger's account are risky and considered deceptive by lenders." That is a competitor's characterization on a page selling an alternative, and it is reproduced here as evidence of what Experian says rather than as a regulator's finding.
