backlinks of spammy or harmful and copycat servers

I uploaded my multilingual versions of the Periodic system of EAV pdf to display on academia.edu (see explication on my multilingual download pages).

All other sites displaying my actual or earlier publications (including the multilingual atlas or medicinal plant pdf samples) without my permission – some especially manipulating the search engine results and asking for donations for their absolutely unauthorized hosting of my papers on their sites … avoid these dishonest competitors.
