I concur with the feeling with some of fellow members that if we feel that if the person (student) has done some work on his/her own and just need some direction and guidance to proceed then … it is OK to help. I like to provide some generic basic model on which the student can explore. I use this type of approach at work to guide junior members of our team.
We try to remove all homework type questions but some get thru. You can always report objectionable content. My best advice is to just not respond.
If you show them the answer what have they learned? Show them where to start looking and he will remember the next time. A gentle nudge in the right dirrection should do. Or you can do his home work for them.. Which is why they call it home work. It is supposed to start them thinking.. My 2 cents
