FoAntiDupe

!FoAntiDupe cover image

FoAntiDupe helps staff catch suspicious item duplication without instantly interrupting normal gameplay. It flags configured item amounts, sends clear staff alerts, and gives reviewers a fast path from the alert to the player's live inventory.

Features

• Review-first anti-dupe detection - flags suspicious inventory and drop amounts for staff review instead of cancelling actions by default.
• Ready-made high-value presets - ships with configurable Lifesteal/SMP-focused rules for diamond blocks, netherite, ancient debris, enchanted golden apples, shulker boxes, and other stash items.
• Broad event coverage - can scan after inventory clicks, inventory drags, item pickups, item drops, crafting, and player joins.
• Nested stash detection - counts matching items inside shulker boxes and bundles so hidden bulk storage still matches the configured rules.
• Clickable staff alerts - staff see the player, rule, amount, and reason, then can click straight into the flagged player's live inventory.
• Admin rule editor - manage rules in-game, add rules from a held item, tune inventory/drop thresholds, and choose exact item, name, lore, enchant, or custom model data matching.
• Audit-friendly logging - writes flag and review activity to the plugin's own latest log file for later staff follow-up.
