Question: if we copy anything from the Internet, and then just write that everything is taken from Google, is that correct?
This reference is incorrect because it leads nowhere, but the posts are not plagiarized. I believe the forum needs to understand the difference between citation and reference; they are often used interchangeably, but they are not the same thing; in academic publications, both are required, but I do not believe they are required on the forum; if you want to cite a few contents from the internet, you should simply put them in a quote; a link is not required; a reference source is only required when you copy/paste a full article
this is plagiarism for sure, let's look at the wide picture.
He finds some text on Google

and post it here. without any discussion on his part and a possible explanation as to why he quoted it.
So, what is next? He will create 20 new topics per week, copy/paste something over the internet, put "Source:
Goggle" and voila, he fulfils signature requirements. he did not even participate in the further discussion on the topic, he may not even understand what he wrote. certainly this was written just for the signature campaign or hunting for merit. (Opening useful topic in Beginners and Help section, easy can bring some merits)
do we really need such posters here?
