How to prevent copy paste of content - copyright protection

Could any of these methods be employed in grav to make it more difficult (not impossible) for someone to copy-paste the content of pages, please?

I saw a "common ninja" plugin but they want nearly $250/yr to use it (after the 300 page view free trial).

Thanks!

It's a pretty futile pursuit and this is not a Grav question.

So, your answer re. grav is that the code won't cause problems in grav - you just don't think it's worth the effort?

@nginxgrav - you can easily incorporate the linked javascript (jquery) code in a grav child theme via custom template, just see the docs
