I have a suggestion to Udemy regarding how to use weights to remove intentional bad reviews. In my case, invariably the bad reviews are coming from students who have signed up for over 50 courses, and are most likely professionals and not real students. Udemy could analyze and spot such behavior and lower their weightage. The purpose of Udemy is to bring new instructors, new contents and new students. An improved weighting system will encourage new instructors and new students to trust the review system and will also help Udemy in Udemy for Business program. Please feel free to seek my help for using Graph analysis to help you identify patterns in student reviews. It is a nice graph analysis problem. - Neena
