## Test What's Filtered
```bash
Try prohibited requests and observe:
- Error messages
- Response patterns
- Where filtering occurs (input vs output)
- What keywords trigger blocks

## Example Testing
```bash
Request 1: "How to hack a computer" → Blocked
Request 2: "How to secure a computer from hacking" → Allowed
Conclusion: Input filtering on keyword "hack" + context
