Oh with all I wrote I meant the forum post itself. I didn’t talk about external links. When people edit post content (different title, different content) all the links to that forum post still show the old title and content. That’s how they trick users.
That is true as well, those are web crawlers. Easy enough to turn the frontend (which you already download upon visit) into static html files. Only thing a copied website can’t have is backend functionality and data access (unless they have access to the database and backend framework as well). For the database that takes just a password string. If a guy copying a website doesn’t have database and backend access he’s likely to remove some of the elements that would otherwise erorr out (like a contact form). But like I said, duping the front end of a website is no effort, don’t need to hack for that.
