During peer assessment, the possibility for the learner to report another peer through a report button. If the person sees an inappropriate response (e.g. a text unrelated to the prompt), or received an inappropriate review from a peer (no constructive feedback, only “well done!” despite the instructions asked for a detailed feedback). they should be able to click “report” for that specific user, which will then notify the course instructor (e.g through an automatic email).
The process for spotting inappropriate responses is way too convoluted.
