What is "plagtracker"

PlagTracker is a Ukrainian-based online plagiarism detection service that checks whether similar text content appears elsewhere on the web. It was launched in 2011 by Devellar.

PlagTracker is used by content owners (students, teachers, bloggers, researchers) to detect cases of "content theft", in which content is copied, without the permission of the author or owner, from one site to another. Many content publishers also use it to detect cases of content fraud, in which old content is repackaged and sold as new original content.
