[ADVANCED] Bypassing DataDome: Canvas Fingerprint Spoofing

DataDome is the most aggressive anti-bot system on the market. It doesn't just check your IP; it uses Canvas Fingerprinting to analyze how your browser renders graphics. Here is how to spoof it using Puppeteer.

---

The Canvas Injection Method:
You must inject a script that subtly alters the pixel output of the HTML5 canvas element before the page loads. This creates a unique but legitimate-looking fingerprint on every execution.

await page.evaluateOnNewDocument(() => {
  const originalGetContext = HTMLCanvasElement.prototype.getContext;
  HTMLCanvasElement.prototype.getContext = function(type) {
    const context = originalGetContext.apply(this, arguments);
    if (type === '2d') {
      const originalFillText = context.fillText;
      context.fillText = function() {
        // Subtle pixel manipulation to spoof the hash
        context.fillStyle = `rgba(0, 0, 0, 0.01)`; 
        originalFillText.apply(this, arguments);
      };
    }
    return context;
  };
});
