### Why Choose DupeTrace?<\/p>\n
**Item duplication exploits are the #1 threat to server economies.** A single dupe glitch can:
\n– Destroy months of careful server balancing
\n– Make legitimate players quit in frustration
\n– Crash your economy overnight
\n– Force rollbacks that punish innocent players<\/p>\n
**DupeTrace stops dupes BEFORE they spread** by:
\n– \u2705 Tracking every non-stackable item with invisible UUID fingerprints
\n– \u2705 Detecting when the same item appears in multiple locations simultaneously
\n– \u2705 Auto-removing duplicates in real-time (configurable)
\n– \u2705 Logging complete forensic histories for investigations
\n– \u2705 Working passively without breaking other plugins or game mechanics<\/p>\n
**Built for performance.** DupeTrace uses asynchronous database operations, connection pooling, and smart caching to handle **200-1000 events\/second** without impacting your server TPS.
\n(equal to 10-50 players actively spamming non-stackable item events. you’re fine)<\/p>\n
