Please use the report feature on any listings that clearly mislead, misinform, or deceive potential buyers in the marketplace, as well as listings that make claims with no supporting proof, as outlined in the rules. It's one thing to voice an opinion in a discussion forum (allowed) and another thing to deceive or misinform a potential buyer in a binding marketplace sales listing to artificially/falsely inflate the price (Not allowed).
If it's not reported, chances are a moderator is not aware of it, as moderator teams do not actively go looking for minor rule violations and rely on members to report such concerns to bring them to our attention.
In some cases, the listings in violation are simply because the seller is new and was unaware or that the seller failed to read the rules. In other cases, sellers deliberately violated the rules to take advantage of uninformed buyers by using false claims. Each case is investigated independently from one another to determine the seriousness and intent of the offense.
We hope that helps.
