+### NSFW-Only Filtering Mode
+
+For communities that only want to filter sexual content while allowing other content types:
+
+```
+!ai nsfwonly true
+```
+
+**When enabled:**
+- ✅ **Blocked:** Sexual content, nude images, explicit material
+- ❌ **Allowed:** Violence, harassment, hate speech, self-harm content
+
+**When disabled (normal mode):**
+- ✅ **Blocked:** All inappropriate content categories
+
+This mode is useful for gaming communities, mature discussion servers, or communities with specific content policies that allow violence but prohibit sexual material.
