ADVANCED FEATURES EXPLAINED
══════════════════════════════════════════════
GEO-VELOCITY DETECTION:
Catches players who connect from different countries in impossible timeframes.
Example:
• Player connects from USA at 3:00 PM
• Player connects from China at 3:30 PM
• Distance: 10,000 km in 30 minutes = 20,000 km/h
• VERDICT: BLOCKED (Impossible travel - commercial flight is 800 km/h)
CONNECTION FINGERPRINTING:
Creates unique device fingerprints to track ban evaders across accounts.
How It Works:
• Combines: IP Subnet + Client Brand + Protocol Version
• Generates SHA-256 hash
• Tracks all accounts using same fingerprint
• Flags if > 5 accounts share one fingerprint
Catches:
• Ban evaders using VPN with new accounts
• Alt account abuse from same device
• Account sharing detection
SMART CACHING STRATEGY:
Three-tier intelligent caching system for maximum performance.
Tier 1: Local Caffeine Cache (0.01ms)
• Positive cache: 24 hours (VPN/Proxy confirmed)
• Negative cache: 1 hour (Clean IP)
Tier 2: Subnet Cache (0.5ms)
• Entire subnet flagged if confidence ≥ 80%
• 10% confidence reduction for subnet matches
Tier 3: Redis Distributed Cache (2ms)
• Shared across multiple BungeeCord proxies
• Automatic serialization/deserialization
• Key prefix: "ftw_antivpn:"
Adaptive TTL:
• 90%+ Confidence → 2x Cache Time
• 75-89% Confidence → 1.5x Cache Time
• <60% Confidence → 0.5x Cache Time
TRUST SYSTEM:
Automatically whitelists legitimate players after proven clean logins.
Configuration:
• Requires 5 successful logins
• 30-day trust period
• Resets on suspicious activity
• Bypass VPN checks entirely
Benefits:
• Reduces API costs by 60%+
• Instant connection for trusted players
• No false positives for regulars
OFFLINE MODE FAILOVER:
Graceful degradation when external APIs are unavailable.
Triggers After: 5 consecutive API failures
Falls Back To:
• Offline threat database
• ASN blacklist
• Built-in detectors only
Recovery:
• Tests API every 60 seconds
• Auto-restores when APIs return
• Discord webhook notification
LOGIN QUEUE SYSTEM:
Prevents API rate limit abuse during login storms.
Features:
• Max 20 concurrent checks
• Queue size: 100 players
• 30-second timeout
• Priority system (VIP support ready)
• FIFO processing
══════════════════════════════════════════════
⚙️ CONFIGURATION
══════════════════════════════════════════════
DETECTION STRATEGIES:
1. PRIORITY-FALLBACK (Recommended):
• Queries providers by priority
• Stops early on high confidence
• Saves 80% API costs
• Max providers to check: 5
• Early exit on 85% confidence
2. QUERY-ALL (Maximum Accuracy):
• Queries ALL providers
• Consensus-based decision
• 60% agreement needed to block
• Best for strict security
3. PARALLEL (Fastest):
• Built-in + APIs simultaneously
• Combines results intelligently
• Sub-second detection times
CONSENSUS SYSTEM:
Prevents false positives by requiring agreement between providers.
Example:
• 5 providers checked
• 3 say VPN (60%)
• 2 say clean (40%)
• Threshold: 60%
• VERDICT: BLOCKED
Adjustable threshold: 50-90%
ACTION MODES:
• KICK - Block connection immediately
• NOTIFY - Allow but alert admins
• BOTH - Block and notify
CONFIDENCE LEVELS:
• 90-100% - Guaranteed VPN/Proxy
• 75-89% - Very Likely VPN
• 60-74% - Probably VPN
• 40-59% - Suspicious
• 0-39% - Clean/Uncertain
