This question already has an answer here:
I am currently undertaking a course in topology, and I've noticed a particular user post many questions which are taken directly from the past two assignments we've been given. They joined about a month ago, and appear to have created the account in large part for the purpose of having this community solve their assignment problems for them.
What is the attitude of this community toward this sort of behaviour, and before elevating the issue with my university, are there actions here on stackexchange I might take to try to discourage the behaviour? i.e. should I report their questions, comment on their posts by linking the assignment papers, or contact a moderator?
