OOPSpam vs WebDecoy

OOPSpam spam filtering API vs WebDecoy bot detection. Content analysis vs multi-signal detection, which you need depends on your threat.

OOPSpam and WebDecoy answer different questions. OOPSpam: “Is this content spam?” WebDecoy: “Is this a bot?” Understanding this helps you choose the right tool, or use both.

Key Difference

The fundamental distinction:

Key insight: OOPSpam catches spam content regardless of source. WebDecoy catches bots regardless of content.

Detection Comparison

Why WebDecoy Catches Bots Better

OOPSpam analyzes what was submitted. WebDecoy analyzes who submitted it:

// Illustrative example (simplified, not WebDecoy's output format):
// WebDecoy flags a bot BEFORE submission
{
  "signals": {
    "tls": {
      "claimed": "Chrome/121",
      "actual": "Playwright",
      "mismatch": true,
      "score": +45
    },
    "honeypot": {
      "hidden_field": true,
      "score": +50
    },
    "behavioral": {
      "form_time": 150,  // 150ms (too fast)
      "score": +25
    }
  },
  "threat_score": 95,
  "verdict": "block"
}
// Flagged regardless of content quality (blocked if enforcement is on)

A bot submitting perfect English with no spam indicators still gets caught by TLS fingerprinting and honeypots.

Block the Actor, Not the IP

OOPSpam scores a submission’s spamminess. But it offers no network identity to block, so a spam bot rotating IPs keeps coming back.

WebDecoy adds the layer a content filter can’t: a persistent actor identity. It correlates every request into an identity built from the TLS handshake (JA4, which a proxy can’t rewrite) plus device and behavioral signals, so a spam bot rotating through thousands of residential IPs is recognized as one actor. When that actor is a confirmed rotator with a non-browser JA4, a Block actor at WAF response action can push a JA4-based rule into your own AWS WAF, or into Cloudflare if your zone has Bot Management (Cloudflare’s Enterprise add-on), so the block follows the actor across the IPs it rotates to. The rule lives in your account where you can inspect it, and it is never built from a browser-like fingerprint real users could share. Automatic blocking from detections is held off until scores are calibrated, so today you review and apply blocks yourself. That’s enforcement a spam-scoring API simply doesn’t offer.

When to Use Each

OOPSpam Only If:

• Spam content is your only problem
• You need to filter human-generated spam
• Bots aren’t a concern

WebDecoy Only If:

• Bots are your primary problem
• You face scrapers, credential stuffing, or automation
• Content quality isn’t the issue
• You need vision AI detection

Both Together

For comprehensive protection:

• WebDecoy: Block bots before they submit
• OOPSpam: Filter spam from humans that gets through

This catches:

• Bot spam (WebDecoy blocks before submission)
• Human spam (OOPSpam filters content)
• Scrapers (WebDecoy detects)
• AI agents (WebDecoy’s FCaptcha has signals designed for them)
