its also visible that he simply answered by inserting the text that the other user brought in - as if he was not plagiarizing, but the author of the answer

I don't quite understand this.

From what I gather, the situation is as follows:

The user found an answer to a question from another site. [perfectly fine]
The user decided to copy the exact text from the site. [perfectly fine*] *(given negation of the following)
The user did not credit the source of the original text. [not fine].

It's a little weird that you're being so vehement towards your friend/colleague's account and that they haven't written a single word of their own to defend themselves.

Forum rules are easy to find. I read them on my first day, IIRC.
