I think someone may have stolen your 2011 theme.
They uploaded 4 styles to userstyles.world that all blatantly copy of your 2011 styles but with RoPro. Same images, Same theme, Different uploader.

xammad made the other themes before lego savant did

plus he was the first person that made the dual layer header

(But yes, he did copy some of the code.)
