How will the publication of other people's articles affect the site?

Question

Search Engine Optimization

In the footer of many sites, you can see something like this warning: “All rights reserved. When using site materials, a prerequisite is the presence of a hyperlink to the page where the original article is located.

It turns out that I can take articles from this site and publish them on my site (by posting a link).

How does this threaten the site-acceptor?
Is there a risk of being filtered?
Does the age of the site affect the consequences?

Answer 1

You can if you don't get hit by the DMCA. It is better to agree in advance with the content owner.
It's hard to get under the filter for this. If you take the content as a basis, add new materials and improve it in every possible way, then you can even stand higher than the "original".
The age of the site alone is such a measure. In general, look at the "trust" of the resource.

Answer 2

Well, stealing articles and completely rewriting them is a common thing, it’s not clear why some other link should be indicated at the same time.
If you just copy-paste, then the little things are purely for updating, for example, news, where the news is absolutely not the main thing on the site
