The project submission contains significant contradictions and red flags. The description details a coffee culture newsletter, while the business type is listed as 'Financial media insights'. The URL provided (filtercoffee.substack.com) does not appear to host an active or indexable publication. Most critically, the traction claim 'most people have used my product' is factually impossible and hyperbolic, indicating a lack of serious reporting. Due to the unverifiable URL, conflicting information, and false traction claims, the project scores below zero.
