This is what we see when the duplicate answers auto flag is raised:
It's not immediately obvious that the same user (red) has posted the same answer to two (or more) questions. The "Answered x mins ago..." is buried in the flag between the details of the asker and the answer text. The asker's profile is also given equal weight. It doesn't matter who asked the question, for this flag they're not important.
This means I have to scan the list looking for multiple lines under the "duplicate answers (auto)" heading.
Can the answerer's details be made more prominent? Either made larger or placed on the right of the flag details box.
In this example the posts are consecutive but I've seen examples (which was also true in the old UI) where other answers were interspersed inbetween answers from the same user. This makes it even harder to spot whether someone is posting not just two duplicate answers but multiple duplicate answers. These cases are more likely to be spammy. Can all answers from the same user be posted consecutively.
