Edge Config: first line of defense against script kiddies

Mux, a company that focuses on developer experience, faced issues with their documentation feedback form being exploited by users attempting to break the intended usage. They initially implemented sanity checks and protections against SQL and code injection but were still receiving hundreds of invalid submissions per hour. To address this issue, they used Vercel's Edge Config feature to block repeated bad feedback and IP addresses without requiring a full deploy each time an update was needed. This solution allowed them to maintain their developer-focused product while ensuring the quality of user feedback.
