This user should not only receive negative trust rating but should also be banned. Copy-pasting content is prohibited in this forum, right? This is totally a type of copy-pasted post. If I wer the admin here I surely ban this user.
The bannable offense is plagiarism, which is taking the content of others and passing it of as yours. Copying and pasting your own content repeatedly is very abusive spamming but it's not plagiarism and if spamming attracts a ban, it should be a temporary ban first.
