Proof of Usefulness Score
Category Standard

Mobile.de is Germany's largest vehicle marketplace, a verified market leader with massive scale (approx. €430M+ annual revenue, 50M+ monthly visits). However, the submission quality is critically low, providing vague claims ('everyone', 'most people') and inaccurate financial data ('75M marketcap' vs actual multi-billion valuation/hundreds of millions in revenue). The score reflects the project's immense real-world utility and dominance, heavily penalized by the lack of direct evidence in the submission.
