Does it make sense to prohibit the Yandex robot from links such as /news?

Question

Search Engine Optimization

It makes sense to prohibit the Yandex robot from links such as /news /news/page-2 and so on. displaying lists of news (title, preview text) if I use a sitemap that gives the robot direct links to news (internal) ?
and the second question about categories, in principle, the same news is duplicated there as in news, but only by category, you need to close them through robots.txt&

Answer 1

No, this is more idiotic.

Answer 2

No need to ban anything, search engines don't like bans.
Use rel=”canonical"

Answer 3

1. No need to ban, use rel=”canonical" in pagination
2. If there is nothing unique there, you can ban it, if there are at least 200 characters of unique text, for example, a category description, then you don’t need to ban it.
