How to keep people from reading

Its an interesting conundrum. I believe it used to be, at least in the US, 25 years of copyright, then you could extend up to two more times *if* you could prove that your "novel" contribution should not be used by others.

In the US is 70 years after the creator's death for works published after 1978.
That avoids situations like Charlie Chaplin had, in which he had to make a few changes to his older movies so he wouldn't lose the copyright while still alive.

Personally, I think any entity that poses such a challenge should have the burden of proving that said challenge is legit. As it stands now, they just quote DMCA and the site takes it down without recourse. Your only recourse as the poster is to sue them. Lawfare should be illegal as well. Just my 2 cents.

That's why registration of any work is recommended, so the creator can prove easily they were the original creators.
