Essay-writing firms claim that they use a service offered by Turnitin, a plagiarism detection tool used by universities, to provide their customers with reassurance that the work they purchase will not be flagged as suspicious.
OK. Tool to detect p[algiarism exists. So, people wanting to avoid plagiarism will use tool to do so.
And, obviously, those selling the essays will use the tool to ensure that the tool used to try to find them doesn’t.
All obvious enough.
When a student or staff member at a subscribing institution runs a Turnitin check using that institution’s subscription, the article that they are assessing is often added to the Turnitin “student database” so that future submissions can be checked for plagiarism against its content. However, when an individual uses the WriteCheck service, essays are not added to the main database.
Access to the WriteCheck service costs $7.95 (£6.40) for one paper, $19.95 for three papers or $29.95 for five papers. HE registered with the service and had one article checked. At no point in the process were we required to verify our identity or say why we were using the service.
The essay mills aren’t paying to have stuff checked individually, don’t be stupid. They’re employing a student with access to an institutional account to do it.
