FoxChat 7-Layer Spam Shield

The 7 Layers

• Layer 1: Rate limiting -- max messages per minute per visitor
• Layer 2: Pattern matching -- known spam phrases, URLs, phone number harvesting
• Layer 3: Behavioral analysis -- typing speed, message timing, engagement patterns
• Layer 4: Content classification -- AI classifier (Claude Haiku) scores each message as REAL or SPAM
• Layer 5: Repeat offender tracking -- visitors who triggered spam filters before get stricter thresholds
• Layer 6: Community blocklist -- spam patterns detected on any FoxChat site are shared across all sites
• Layer 7: Bot detection -- headless browser detection, suspicious fingerprints, impossible timing

Community Protection

When a spam pattern is detected on one FoxChat site, it is automatically shared with every other FoxChat site. This means new customers benefit from the spam protection built up across the entire FoxChat network from day one. No configuration needed.

Zero Friction for Real Users

Unlike CAPTCHA-based systems, FoxChat never asks real users to prove they are human. All 7 layers operate silently in the background. Real users never know the spam filter exists -- they just have a clean, fast chat experience.
