+670
Proof of Usefulness Score
Category Standard

The submission represents Y Combinator, a premier global startup accelerator with immense real-world utility and reach. However, the submission data itself is of extremely poor quality, containing factual errors (Launch Date 2019 vs 2005) and lazy evidence ('most people have used my product'). The high score reflects the verifiable reality of the entity associated with the URL, heavily discounting the 'Response Quality' and 'Evidence' sections due to the lack of effort in the application. A score of 670 places it in the 'Much larger scale' category, appropriate for YC, but capped below the maximum potential due to the unverified nature of the specific submitter 'MysticBlade'.
