Allow me to express my opinion. I believe that posting a general link to a resource, instead of a specific link to the text being posted, is unacceptable. There should be a link directly to the text that is copied and posted on the forum. In any case, these are the requirements in our Russian section. Also, when copying and pasting text, a user comment must be present. In our Russian section, we have two notes to the forum rules which govern such behavior:
7. Posts must be original. Posts made on the principle of copy-paste from another resource is not allowed, if such posts are made specifically to increase the number of posts. Such posts fall under the first point of the rules.
...If you copy text from the Internet, in addition to linking to the source, you should share your constructive opinion about it, so if you have nothing to say, then there's no reason to post someone else's text.
