Four questions from this person have been answered by the same member and appear to contravene what is said here: -
How do I ask and answer homework questions?. In particular, this advice is given: -
Providing an answer that doesn't help a student learn is not in the student's own best interest. Therefore you might choose to treat homework questions differently than other questions.
The member making those answers has been previously informed about making this type of answer a couple of times to my recollection. Many of us are guilty of this (including me); it's easy enough to slip into making an answer that can be used almost verbatim for homework purposes but, a stern word or two usually prevents recurrence.
What should be done about this?
Do we do anything about it?
I've downvoted said questions and answers but I'm not really sure that this is effective or desirable.
