Report profile? So what does that have to do with plagiarism, you are not reporting a profile, but some kind of content that has to do with that profile. Given that the posts in question have been deleted, the only thing someone can do now is to find new plagiarized posts (if they exist) and then make a report.
Maybe my choice of text was misunderstood. Obviously, when you report a profile, it means you are going to report a post, like the one quoted in the OP about plagiarism by a certain profile. The profile is the culprit.
