I think there's a reason why this user doesn't got banned yet, because you and one other user have reported his few posts for many times.

1. Incorrect original source
2. Incorrect original source
3. Bad quotation
4. Incorrect original source
5. And the recent one you posted fall to incorrect original source

The moderators might think he have no intention to plagiarism because he have wrote https:... which is he show if he was copy pasted from somewhere. For the case 3 he have mentioned according to, so he have let anyone know if it's not come from his words.

Maybe if there's a post where he not mention anything related to original source, he will get banned, just like how the above newbie user got banned.
