[scribus] Security on exported PDF

[John Jason Jordan]

I have a book that I'm about to lay out, preferably with Scribus, and
it will be published in PDF format. (The first time I've ever done
that.) Sales will be over the internet, so I'm trying to figure out how
I can stop piracy.

I started by creating a one-page dummy .sla file with just a text frame
filled with Lorem ipsum. I exported it as PDF and on the Security tab I
deselected all the options, including no copying and pasting, and
exported the file. Then I opened the file in Evince (Xubuntu 16.04),
which required the password that I set to open the file, but once the
file was open I could copy and paste the text.

I think I don't understand what I'm doing here. And I may be going
about this the wrong way. Perhaps there is a completely different
approach. After all, if I require a password to open the file a pirate
can just send the recipient the password along with the PDF.

I'm scratching my head here. I need some suggestions!
