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. In July 2011, the website sees 20 percent of visitors coming from Asia out of its 5,000 daily visitors. The US is the number one biggest user of the site, with India in second place. Other heavy users are Malaysia, the Philippines, Pakistan, and Singapore, all in the top 10.
