# Moat LMS Blocker - uBlock Origin Filter Lists

Filter lists for [uBlock Origin](https://ublockorigin.com/) that block
communications between eLearning content and Learning Management Systems (LMS)
or Learning Record Stores (LRS).
Useful for debugging eLearning content and LMS integrations by preventing
tracking data from being sent to the server. For example, block xAPI to test
fallback to SCORM, or block SCORM 1.2 and SCORM 2004 to test fallback to AICC
HACP.
**Why MOAT?**
Once upon a time I had greater ambitions for a "Multi-protocol Online Analytic
Tool" for elearning to isolate content from the LMS castle. _Or perhaps it was_
_vice versa?_ This is the polished version of hacks I made about ten years ago.
## Installation for uBlock Origin (Recommended)
uBlock Origin requires manual import of filter lists. Follow these steps:
1. Open uBlock Origin dashboard (click the uBO icon, then the gear icon)
2. Go to the **Filter lists** tab
3. Scroll to the bottom and check **Import** under "Custom"
4. Paste one or more of these URLs:

## Toggling Filter Lists
Each subscribed filter list appears with a checkbox in the uBlock Origin Filter
lists tab. Uncheck to disable, check to enable. Click **Apply changes** after
toggling.
## Browser Compatibility
| Browser | Support |
|---------|---------|
| **Firefox** | Full support |
| **Edge** | Full support |
| **Chrome** | Limited (use [uBlock Origin Lite](https://chromewebstore.google.com/detail/ublock-origin-lite/ddkjiahejlhfcafbddmgiahcphecmpfh)) |
| **Brave** | Full support |
| **Opera** | Full support |
Note: Chrome's Manifest V3 restrictions limit uBlock Origin functionality.
Firefox and Edge provide the best experience.
## What Gets Blocked
### SCORM 1.2 & 2004
- Runtime library scripts (scormdriver.js, APIWrapper.js, etc.)
- LMS API communication files
- Common authoring tool output (Articulate, Captivate, Lectora)
### xAPI (Experience API)
- Statement endpoints (`/xAPI/statements/`)
- Agent and activity endpoints
- State and profile endpoints
- TinCanJS libraries
- Common LRS paths (`/tcapi/`, `/lrs/`)
### cmi5
- Launch parameters (fetch, registration, activityId)
- Course structure manifests (cmi5.xml, tincan.xml)
- Authentication endpoints
- cmi5 client libraries
### AICC
- HACP protocol commands (getparam, putparam, exitau, etc.)
- AICC communication files

universal adblock filter list linter that checks for syntax errors and validates
uBlock Origin filter syntax.
