 * Tests the full flow:
 * 1. Nickname modification with content security check
 * 2. Chat message with real-time check
 * 3. Signature/description modification with check
 * 4. Avatar upload with image check
 * 5. Report submission
 * 6. Auto-takedown after 3 reports
 * 7. Mute penalty after violations
