It would be really helpful if we were able to get alerted to potential plagiarism in both RI and CodeInterview. In a live coding challenge, detecting the plagiarism in real-time and getting a link to the site where it was found would be extra helpful so we could ask some targeted follow up questions. On the one hand, I expect developers to use the internet both during a code challenge and in their day job. On the other hand, a copied solution often isn't well understood, so getting feedback that the code might be plagiarized could allow the interviewer to ask probing questions to make sure the candidate actually understands the solution.
