You can always mark a mod as "deprecated", to make it "hidden" until it's ready to go full public.
I gave it another look, and saw some differences with my mod, so its not really an exact copy, but the thumbnail, description and a few files are identical, including my stupid "no" license, which contradict the MIT license, and says i'm the author of the mod which i'd appreciate if it was changed.
If you need any help i can try to provide, but i'm no good modder, that's why i started by the lab as a test.
