Someone uploaded copies of your extension to AMO:

Rec Wizard
RecMaster
RecMode Control
Recommendation Master
RecSavvy
RecSense
YouTube Recapture
YouTube Recommendation Control
YouTube Recomode
YouTube RecoOptimize
YouTube RecXpert

All of these extensions have the same manifest.json and README.md as YouTube Focus.

The Homepage links point to your Github repo.

The Support Site or user Homepage links are SEO spam.
That's why I didn't include links to the extensions.
But if you want, I'll post them.

How I found out about the problem:

(I'm not the OP)

If you want to report the clones, the relevant Add-on Policies are:

• If the add-on is a fork of another add-on, the name must clearly distinguish it from the original and provide a significant difference in functionality and/or code.
• Add-ons with the sole purpose of promoting, installing, loading or launching another website, application or add-on are not permitted.
