Wondering

Say you copy the content on darkweb, would you be able to make money from it? The content on darkweb is not on clearnet soo there is no duplicate content. Sorry for noob question, im really wondering...
thank you

Dont know what Darkweb is but if you copy the content and post it on your site, it will become duplicate content

You are asking if you can profit from selling kids, kidneys and weed? Yes you can. Should you? Not in public. Thats why most of the deep net stays on the deep net.

Other stuff, like non indexed forums, government libraries, etc, all can be used, but if they are ever indexed, you are out of luck.
