INFINITIGUARD
The Ultimate Anti-Dupe & Anti-Exploit Protection
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Stop dupers, exploiters, and crashers before they destroy your economy.
InfinitiGuard is a comprehensive, all-in-one security plugin that patches 30+ known exploits across every attack vector — from illegal items and duplication glitches to crash exploits and lag machines. Every protection is individually configurable, every violation is logged, and your staff is alerted in real time.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
FEATURE OVERVIEW
ILLEGAL ITEM DETECTION — 9 Checks
- Overstacked Items — Detects and fixes items stacked beyond their vanilla maximum. Option to auto-fix to correct stack size instead of removing.
- Illegal Enchantments — Catches enchantments exceeding max levels, wrong item types (Sharpness on a helmet), and conflicting combinations (Silk Touch + Fortune). Every enchantment limit is individually configurable.
- Illegal NBT Data — Removes items with oversized NBT, excessively long display names, and bloated lore that cause lag or crashes.
- Banned Materials — Automatically confiscates bedrock, barriers, command blocks, debug sticks, spawners, and other unobtainable items from survival players. Fully customizable blacklist.
- Crash Items — Detects and removes crash books (oversized pages), crash banners (excessive patterns), and crash fireworks (explosion overload) before they can affect anyone.
- Negative Durability — Catches items with negative or overflowed damage values that make tools unbreakable.
- Illegal Attributes — Detects items with absurd attribute modifiers (999 attack damage, infinite speed, etc.) with configurable maximums per attribute.
- Illegal Potions — Removes potions with beyond-vanilla amplifiers or durations.
- Shulker Nesting — Prevents shulker boxes inside shulker boxes that enable exponential item storage exploits.
DUPE PREVENTION — 13 Checks
- Entity Inventory Dupe — Prevents donkey/llama/mule inventory duplication. Auto-closes inventory when entity takes damage, dies, enters a portal, or player moves too far away.
- Crafting Dupe — Blocks shift-click race condition exploits and empty-ingredient result slot manipulation.
- Death Dupe — Verifies Totem of Undying actually exists in hand before resurrection. Snapshots pre-death inventory to detect item duplication.
- Gravity Block Dupe — Detects duplicate falling block entities spawning at the same location (sand, gravel, concrete powder, anvils).
- Portal Dupe — Blocks item drops near nether/end portals, cancels young item entities entering portals, and prevents cross-dimension item duplication.
- Disconnect Dupe — Takes inventory snapshots during container interactions. Restores flagged players to last known good state on disconnect.
- Drop/Pickup Dupe — Rate-limits item drops and pickups per second to detect automated dupe scripts and rapid drop-pickup cycles.
- Chunk Boundary Dupe — Closes inventories when container chunks unload. Blocks interaction with containers in unloaded chunks.
- Dispenser Dupe — Rate-limits dispenser firing and verifies dispensed items actually exist in the dispenser inventory.
- Piston/TNT Dupe — Blocks TNT, rail, carpet, and string duplication via piston mechanics with individual toggles per material.
- Workstation Dupe — Protects all crafting station result slots (anvil, smithing table, grindstone, loom, stonecutter, cartography table, beacon) from shift-click, number key, and offhand swap exploits.
- Villager Trade Dupe — Prevents disconnect-during-trade duplication, rapid trade execution, and trade slot manipulation. Safeguards items on unexpected disconnect.
- Inventory Transaction Guard — Global click rate limiting (anti-autoclicker), cross-boundary drag exploit prevention, and hopper transfer validation.
CRASH PREVENTION — 4 Checks
- Book Crash — Validates page count, page byte size, title length, and author length on every book edit. Cancels oversized edits before they can be saved.
- Sign Crash — Limits sign line length and strips crash-inducing Unicode characters (directional overrides, zero-width chars, private-use characters).
- Creative Exploit — Blocks creative mode players from spawning items with excessive NBT data or placing exploit items into containers.
- Chunk Ban Fix — Automatically detects chunk-banned players by monitoring rapid disconnect patterns. Teleports affected players to spawn on rejoin. Includes manual
/ig unchunkbancommand.
WORLD EXPLOIT PREVENTION — 4 Checks
- Nether Roof — Blocks movement and teleportation above configurable Y level in the nether. Prevents ender pearl and chorus fruit teleports above the roof.
- Bedrock Break — Protects bedrock, barriers, end portal frames, and end portals from destruction by players or explosions.
- Lag Machine — Limits redstone updates, piston activations, and hopper density per chunk. Automatically neutralizes lag machines without affecting normal gameplay.
- End Portal Exploit — Prevents block placement on/adjacent to end portal frames and end gateways.
