Sharing your work isn't at issue, the builder and seller of Klein Bottles is here as are many other creators.
Two specific things are at play here, the creation of a dedicated account to only promote your work (if that is what is happening here, _I_ make no claims wrt that), and the badgering of a fellow forum user who routinely points out past related links, dupes, etc (as a commonplace occurrence).
If in a day or two you return and reread your own comments here demanding to know who people are and why they make such comments then you might see these exchanges in a different light. The site guidelines linked above are worth the read.
