What do you think posting questions about homeworks?

I think that, people shouldn't post to ask for answers for their homeworks.
I've never posted something for my assignments, because I think it's not fair,because others might have done the assignment by their self, so they should get better grades than me.

Although I'm not totally against, posting some homework questions, but at least a person should show some work, and not post the whole assignment and ask someone to solve it for them.

What about you?
