BlockBlocker Mod for Minecraft
Overview
BlockBlocker is a lightweight utility mod that prevents specific blocks from being placed (world generation, player placement, etc) in your world. Configure any block to be automatically replaced with air when a player or mechanic attempts to place it—perfect for restricting overpowered items, disabling broken mechanics, or creating custom gameplay rules.
Key Features

⚡ Instant Prevention Blocked placements are silently replaced with air at the moment of placement—no lag, no error messages.
🔧 Config-Driven Add/remove blocks via a simple config file. No in-game commands needed—just edit and reload!
