Proof of Usefulness Score
You're In Business
The submission references 'Google Gruyere,' a well-known legacy security training web application developed and hosted by Google, not the submitter. The evidence of traction provided is a generic user session link, confirming the submitter is a user of the tool rather than its creator. The submission lacks original contribution, ownership, or valid traction data, resulting in a near-zero score due to misattribution and lack of verifiable project ownership.
