NoMoreBots

A powerful anti-bot verification plugin for Velocity proxy servers using LimboAPI with hybrid chat + movement verification system.

Features

• Hybrid Chat + Movement Verification: Players complete both code typing and multi-directional movement challenges
• Multi-Direction Movement System: Configurable movement verification (up, down, left, right) with customizable sequences
• Intelligent Cooldown System: User + IP based cooldown to prevent repeat verification for legitimate players
• Timeout Protection: Configurable response timeout with automatic kick for non-responsive connections
• Limbo Integration: Uses LimboAPI to hold unverified players in a virtual limbo world
• Database Tracking: SQLite database to track player verification status, attempts, and cooldown periods
• Configurable Settings: Highly customizable verification parameters, directions, timeouts, and cooldown settings
• Multi-language Support: English and Turkish language files with proper localization
• Admin Commands: Administrative tools for managing verification system
• Attempt Limiting: Configurable maximum verification attempts before timeout action
• Advanced IP Tracking: Prevents same IP different user and same user different IP bypassing

Requirements

• Velocity 3.3.0+
• LimboAPI plugin
• Java 17+

Installation

1. Download the latest release from the releases page
2. Install LimboAPI on your Velocity server
3. Place nomorebots-1.0.0-SNAPSHOT.jar in your Velocity plugins folder
4. Restart your server
5. Configure the plugin in plugins/nomorebots/config.yml

Configuration

The plugin creates a configuration file at plugins/nomorebots/config.yml with customizable:

Verification System

• Chat Verification: Code length, characters, case sensitivity
• Movement Verification: Multi-directional sequence configuration (up:2, left:3, etc.)
• Direction Angles: Precise angle ranges for each direction (up, down, left, right)
• Response Timeout: Maximum time players have to respond (with kick option)
• Tolerance Settings: Angle tolerance for movement detection

Cooldown System

• Track by User: Remember verification by username
• Track by IP: Remember verification by IP address
• Duration: How long verification is remembered (24 hours default)
• Combined Tracking: Require both same user AND same IP for bypass

Database & Performance

• SQLite database configuration
• Async database operations
• Session management and cleanup
• Player data caching

Example Movement Configuration

movement:
  directions:
    - "up:2"    # Look up for 2 seconds
    - "left:2"  # Then look left for 2 seconds
    - "down:1"  # Then look down for 1 second
  
  response-timeout: 20 # Max 20 seconds to respond
  kick-on-timeout: true # Kick if timeout exceeded

Example Cooldown Configuration

cooldown:
  track-by-user: true  # Track by username
  track-by-ip: true    # Track by IP address
  duration: 86400      # 24 hours cooldown

Commands

• /nomorebots reload - Reload plugin configuration
• /nomorebots stats - View verification statistics
• /nomorebots bypass <player> - Bypass verification for a player
• /nomorebots verify <player> - Manually verify a player
• /nomorebots reset <player> - Reset player verification status
• /nomorebots timeout <player> <duration> - Set timeout for a player

How It Works

1. Player Joins: New players are automatically sent to limbo for verification
2. Chat Challenge: Players must type a randomly generated code exactly as shown
3. Movement Challenge: Players complete a sequence of directional movements (configured in config)
4. Cooldown Period: Successfully verified players are remembered for 24 hours (configurable)
5. Smart Tracking: System tracks both username and IP to prevent bypass attempts

Verification Process

Player Joins → Limbo → Chat Code → Movement Sequence → Success → Main Server
                ↓
         (Timeout/Fail → Kicked/Timed Out)

Cooldown Logic

• Same user, same IP: Skip verification (if both tracking enabled)
• Same user, different IP: Require verification (prevents account sharing)
• Different user, same IP: Require verification (prevents IP spoofing)
• New user/IP combination: Always require verification

Building

git clone https://github.com/amhunter1/NoMoreBots.git
cd NoMoreBots
mvn clean package

Advanced Features

Multi-Direction Movement

Configure complex movement patterns:

directions:
  - "up:2"      # Look up for 2 seconds
  - "right:1"   # Look right for 1 second  
  - "down:3"    # Look down for 3 seconds
  - "left:2"    # Look left for 2 seconds

Precise Angle Control

Fine-tune detection angles:

angles:
  up:
    pitch-min: -90.0  # Straight up
    pitch-max: -30.0  # Minimum up angle
  down:
    pitch-min: 30.0   # Minimum down angle
    pitch-max: 90.0   # Straight down

Advanced Cooldown Options

cooldown:
  track-by-user: true   # Remember by username
  track-by-ip: true     # Remember by IP
  duration: 86400       # 24 hours in seconds

Performance

• Async Database Operations: Non-blocking database queries
• Player Data Caching: Reduces database load
• Session Management: Automatic cleanup of expired sessions
• Configurable Timeouts: Prevents resource waste from inactive connections
