This question is for teachers, professors etc. I have noticed so many cases in which students are paying for someone else to get their academic essays, dissertations done. These days I noticed that even many companies(In the UK, US, China etc) are doing it as a business with the cover of supporting/consulting students on research writing. This issue is aggravated with a ('policy') shift of students' assessment towards more of written works, particularly in Social Sciences. Would you reflect your observation, experience or how to deal with such problem???
