My themes are always rejected.

I am a new Firefox user, and I really enjoy the unique themes on this browser. I also wanted to try uploading my own themes to https://addons.mozilla.org/en-US/firefox/themes/. I created a few themes, but they are always rejected with the reason: Content, specifically Spam .

I feel very disappointed that my designs are considered spam. They may not be beautiful, but at the very least, they are not duplicates. I’ve noticed that there are many themes in the store that are identical, sometimes even 3–4 identical images uploaded by different accounts. I think this might impact Firefox enthusiasts who genuinely want to contribute their ideas.

Could someone please explain to me what I did wrong? Before uploading, I tested my themes on several screen sizes and referred to many fixes suggested by the community, but none of them worked.
