If a Learner views an inappropriate Submission during Peer Review, they are able to report the Submission to their Instructor (read more about how Learners flag inappropriate Submissions here). Instructors can respond to inappropriate Submissions by deleting the Submission. If you Delete the Submission, the video is permanently removed from ApprenNet's servers and you will not be able to access the video in the future.
If a Learner comes across a Submission they see as inappropriate, they will submit a report and the Instructor will receive an email notification.
To Delete a Submission, view the Learner's Submission page, select Delete Submission, in the upper right corner. The video then will not appear anywhere in the Exercise and will not be accessible by any Learners. The Learner can then re-submit to the Exercise.
