I once reviewed a journal article that at least a few pages of plagiarized text in it. I noticed only because I thought some sentences sounded like I wrote them, and as it turned out, I did write them. Not surprisingly, I found the paper even worse from a technical standpoint, so I gave it a rather negative review. I tried to be as helpful as possible, even suggesting what they should do instead of what they did. It appears the paper was rejected. Fast forward 6 to 12 months. I found what seems to be a descendant of the paper published in another journal. While the vast majority of the plagiarism I identified was removed, they added some parts plagiarized from my review. I contacted the journal, who replied that plagiarism detection software didn't find anything. I replied that it wouldn't because a confidential review would not be in their system. Plus, I gave them a list of plagiarized parts; all they had to do was check against the paper. I told them that I did not spend much time checking for plagiarism, so for all I know there's a lot more plagiarism in the paper. The journal representative never did anything about the paper, unfortunately. I now refuse to publish in that journal and discourage others from publishing there as well.
