ANTI-SPAM v1.0

---

OVERVIEW Anti-Spam is a high-performance chat security system designed to maintain server decorum and prevent chat flooding. Built with a focus on thread-safety and advanced string-matching, it stops repetitive messaging patterns before they reach your players.

KEY FEATURES - Smart Similarity Engine: Utilizes the Levenshtein Algorithm to identify and block "similar" messages, preventing bypasses like adding a single dot or space. - Per-Player Message Memory: Maintains a rolling buffer of the last 10 messages (configurable) for every online player to detect long-term repetition. - Thread-Safe Architecture: Engineered for Folia using ConcurrentHashMaps and synchronized logic to ensure stability in multi-threaded environments. - Bypass Support: Integrated permission system allowing staff or automated bots to bypass spam restrictions.

COMMANDS AND PERMISSIONS - /antispam reload Refreshes the configuration file and clears the current message history cache. Permission: antispam.admin

SECURITY LOGIC PROTOCOL 1. NORMALIZATION: Incoming strings are trimmed and converted to lowercase for accurate comparison. 2. BUFFER CHECK: The new message is compared against the player's recent historical chat data. 3. SIMILARITY SCORING: If the calculated similarity exceeds the threshold (default: 80%), the message is canceled. 4. NOTIFICATION: The player is issued an instant warning to prevent further repetition.

TECHNICAL REQUIREMENTS - Java 21 or higher. - Paper or Folia 1.21.1 or higher. - Concurrent data handling support.
