I have better things to do than read the whole text (~ 5.100 words) but I did read enough to know that I couldn’t agree with this User Agreement. Instead I decided to write this blog post explaining what I find so disagreeable.
My work can only be used by Turnitin to check for plagiarism.
As I see no reason for it being my responsibility to help Turnitin get better at doing their job (by giving them the ability to recognise when somebody plagiarizes my work), I want Turnitin to delete my work as soon as the check has been done.
If Turnitin relies on third parties to do the plagiarism check, then I would need a limitative list of these parties and the assurance that the above two conditions will also count for them.
