STON.fi does not run a token verification system. The "Unverified Token" status you may see appears in third-party TON ecosystem products such as Tonkeeper and Tonviewer, not in the STON.fi interface.
If you want that status removed in Tonkeeper, the review is handled by the Tonkeeper team through their token-assets repository — see github.com/tonkeeper/ton-assets and our article How do I verify my token? for the step-by-step instructions.
STON.fi has no role in the review process or the final decision on any Pull Request.
