What would be better is solve the root problem. These (illegal, somewhat legitimate) hoarding sites are most valuable for research literature which, given the public funding nature of these things should not be gated to begin with.

The comsequence of resolving the symptoms is that illegitimate use piggy back on it. Artistic literature that would legitimately deserve protection get hoarded as well.

Sweating authors of clearly copyrightable arts, typically novels, manuals, are seeing their work accessed free of royalties. For the sake of freely distributing scientific literature.

It makes it impossible to make then distinction given the legitimate utility is operating in a dark domain.
