As a moderator of the Writing & Reviews community, I have seen all kinds of fraud in terms of plagiarism of content, images and even duplicates of content. From our community we have done a great job to catch offenders, however, these criminals move to other communities to repeat patterns. Is there a way to lower their reputation? Is there a possibility to add them to a blacklist? It would be very good if they could be identified every time they make a Post.
