Lighter's founder, Vladimir Novakovski, has confirmed that the platform employs on-chain data for detecting Sybil attacks through clustering and behavioral analysis. However, the specifics of the anti-Sybil algorithm will remain undisclosed to prevent potential exploitation. Users who believe they have been wrongly flagged can appeal through Discord, with the process involving both internal and external experts. Novakovski noted that the number of appeals is lower than anticipated and encouraged users to submit appeals if they feel misjudged.
