+## Content Protection & AI Scraping Prevention
+
+Sunday Comics includes built-in measures to discourage AI web scrapers from using your creative work for training machine learning models without permission.
+
+### Protection Features
+
+#### robots.txt Blocking
+The dynamically generated `robots.txt` file blocks known AI crawlers while still allowing legitimate search engines:
+
+**Blocked AI bots:**
+- **GPTBot** & **ChatGPT-User** (OpenAI)
+- **CCBot** (Common Crawl - used by many AI companies)
+- **anthropic-ai** & **Claude-Web** (Anthropic)
+- **Google-Extended** (Google's AI training crawler, separate from Googlebot)
+- **PerplexityBot** (Perplexity AI)
+- **Omgilibot**, **Diffbot**, **Bytespider**, **FacebookBot**, **ImagesiftBot**, **cohere-ai**
+
+**Note:** Regular search engine crawlers (Googlebot, Bingbot, etc.) are still allowed so your comic can be discovered through search.
+
+The robots.txt also includes a reference to your Terms of Service for transparency.
+
+#### HTML Meta Tags
+Every page includes meta tags that signal to AI scrapers not to use the content:
+
+```html
+<meta name="robots" content="noai, noimageai">
+<meta name="googlebot" content="noai, noimageai">
+```
+
+- `noai` - Prevents AI training on text content
+- `noimageai` - Prevents AI training on images (your comics)
+
+#### Terms of Service
+A comprehensive Terms of Service page at `/terms` legally prohibits:
+- Using content for AI training or machine learning
+- Scraping or harvesting content for datasets
+- Creating derivative works using AI trained on your content
+- Text and Data Mining (TDM) without permission
+
+The Terms page is automatically linked in your footer and includes:
+- Copyright protection assertions
+- DMCA enforcement information
+- TDM rights reservation (EU Directive 2019/790 Article 4)
+- Clear permitted use guidelines
+
+#### HTTP Headers
+Sunday Comics automatically adds `X-Robots-Tag: noai, noimageai` headers to all responses for additional AI blocking enforcement.
+
+#### TDM Reservation File
+The `/tdmrep.json` endpoint formally reserves Text and Data Mining rights under EU Directive 2019/790, pointing to your Terms of Service.
+
+### Advanced: Image-Level Protection Tools
+
+For artists who want to protect their work at the image level, consider these specialized tools:
+
+#### Glaze (Style Protection)
+**What it does:** Adds imperceptible changes to images that prevent AI models from accurately learning your artistic style.
+
+**Best for:**
+- Protecting your unique art style from being copied by AI
+- Making AI-generated imitations look wrong or distorted
+- Artists concerned about style mimicry (e.g., "draw like [artist name]" prompts)
+
+**How to use:**
+1. Download from [glaze.cs.uchicago.edu](https://glaze.cs.uchicago.edu)
+2. Process your comic images before uploading to your site
+3. The changes are invisible to humans but confuse AI models
+
+**Trade-offs:**
+- Processing time: Can take several minutes per image
+- Slight file size increase
+- Requires reprocessing all comics
+
+#### Nightshade (Data Poisoning)
+**What it does:** Makes images appear as something completely different to AI models while looking normal to humans.
+
+**Best for:**
+- Active defense against unauthorized AI training
+- Making scraped data actively harmful to AI models
+- Artists who want to fight back against scraping
+
+**How to use:**
+1. Download from [nightshade.cs.uchicago.edu](https://nightshade.cs.uchicago.edu)
+2. Process images before uploading (can combine with Glaze)
+3. AI models trained on these images will produce incorrect results
+
+**Trade-offs:**
+- More aggressive than Glaze (may violate some ToS)
+- Processing time similar to Glaze
+- Ongoing research tool, effectiveness may vary
+
+#### Recommendations
+- **Use Glaze if:** You want passive protection for your art style
+- **Use Nightshade if:** You want active defense and accept the risks
+- **Use both if:** Maximum protection is your priority
+- **Combine with Sunday Comics protections:** These tools complement the web-based protections (robots.txt, meta tags, etc.)
+
+**Note:** Both tools are free, open-source projects from the University of Chicago's SAND Lab, specifically designed to help artists protect their work from AI exploitation.
+
+### Important Limitations
+
+**These measures are voluntary** - they only work if AI companies respect them:
+
+✅ **What this does:**
+- Signals your intent to protect your content
+- Provides legal grounding for DMCA takedowns
+- Blocks responsible AI companies that honor robots.txt
+- Makes your copyright stance clear to users and crawlers
+
+❌ **What this doesn't do:**
+- Cannot physically prevent determined bad actors from scraping
+- Cannot remove already-scraped historical data from existing datasets
+- No guarantee all AI companies will honor these signals
+
+**Companies that claim to honor robots.txt:**
+- OpenAI (GPTBot blocking)
+- Anthropic (anthropic-ai blocking)
+- Google (Google-Extended blocking, separate from search)
+
+### Customizing Your Terms
+
+Edit `/Users/pori/PycharmProjects/sunday/content/terms.md` to customize:
+
+1. **Jurisdiction** - Add your country/state for legal clarity
+2. **Permitted use** - Adjust what you allow (fan art, sharing, etc.)
+3. **Contact info** - Automatically populated from `comics_data.py`
+
+The Terms page uses Jinja2 template variables that pull from your configuration:
+- `{{ copyright_name }}` - From `COPYRIGHT_NAME` in `comics_data.py`
+- `{{ social_email }}` - From `SOCIAL_EMAIL` in `comics_data.py`
+
+### Testing Your Protection
+
+**Verify robots.txt:**
+```bash
+curl https://yourcomic.com/robots.txt
+```
+
+You should see AI bot blocks and a link to your terms.
+
+**Check meta tags:**
+View page source and look for:
+```html
+<meta name="robots" content="noai, noimageai">
+```
+
+**Validate Terms page:**
+Visit `https://yourcomic.com/terms` to ensure it renders correctly.
+
+### Reporting Violations
+
+If you discover your work in an AI training dataset or being used without permission:
+
+1. **Document the violation** - Screenshots, URLs, timestamps
+2. **Review their TOS** - Many AI services have content dispute processes
+3. **Send DMCA takedown** - Your Terms of Service provides legal standing
+4. **Contact the platform** - Use your `SOCIAL_EMAIL` from the Terms page
