In the Suggested Edits queue, plagiarism is a rejection reason unique to tag wiki edits. Plagiarized edits can be caught by googling the tag wiki text or by googling the product and examining the most common copy-paste sources: Wikipedia and the product page itself. These edits require an amount of discretion and effort that goes beyond what ordinary suggested edits usually require.
So, I've encountered a few copy-pasted tag wikis in the queue recently and voted to reject them accordingly. However, I just looked at my review history and noticed that at least one of these tag wiki edits was subsequently accepted. I know mods can place a mild ban on editors who accept plagiarized material, but I think that doesn't do much in general to prevent these sorts of review mistakes from happening.
Could we do something feature-wise to reduce the chances of plagiarized tag wiki edits being accepted?
A few ideas:
Place a banner or some other visual flag on edits that a previous reviewer rejected for being plagiarized. Maybe as part of this feature, the banner could link to the source of the plagiarized material. (Providing a link or reference to the source could be a new requirement for voting to reject a tag wiki edit on grounds of plagiarism. This isn't asking much since the reviewer presumably already looked it up.)
Include a web search pane or something similar on the review page. It could show the search results for the tag wiki or the tag. This may not be feasible because of API costs or other reasons, but I'm just throwing it out there. Someone may a have an idea of how this could be implemented effectively.
Similar to the last suggestion, this kind of search could be done in the background and matches meeting a certain threshold could cause the display of a banner or other visual cue that lets the reviewer know to pay special attention to plagiarism. The system does something similar for spam, so this could be an option.
What do you think of these ideas?
First, are the current measures for stopping tag wiki plagiarism good enough? In other words, is it worthwhile to implement further measures to keep plagiarism out of tag wikis?
Second, are the proposed options good? Sound? Feasible? Actionable?
Third, what other ideas do you have for addressing this problem?
