Hi, kchiba!
I'm gonna share my personal thoughts about it and how they changed along the time.
I firstly took as a heresy those questions from students that come to this site for help with their homework and assignments. I tended to believe that it was unfair, so I avoided answering or sometimes posting a slightly ironic comment. I thought that the help (from here) should be delivered to people who needed aid in their work or life, not to cheating students.
At the same time I realized that sometime there were topics with questions that made me talk to myself wondering if that wasn't a clear and neat abuse of the help that could be got at this place. I remember many cases of people who asked almost for a full accounting or selling application for their own business without even helping or facilitating the minimum data. The most extreme that I remember was that of an airline owner who asked for a solution for an optimization of flight scheduling (1: would you -client- rely on such an airline with such a schedule? I don't.; 2) would he -owner- rely on a provided service of such an origin? I don't mean quality. He doesn't.).
Here my answer, which was never returned:

One day I read a comment from Hui about gratitude:
http://chandoo.org/forum/threads/am-i-too-suspicious.3789/#post-19298
and decided to analyze the problem from another viewpoint. Why should be I who decide to help or not a student if with Google he has full access to virtually any question or subject? Will my little grain of sand make the difference? No, absolutely not.
Then I weighted the 2 different cases:
a) Those thankful, very thankful, up to saturation sometimes, mostly but not exclusively students, that cheating or not they try to accomplish a job: their homework or assignment.
b) Those ungrateful and sometimes unpolite, students or not and usually not students, that are clearly trying to take advantage of the collective knowledge not to solve a job or personal issue but to spare a few bucks.
And I changed my mind, I realized I was wrong at a first moment, so whenever I had the chance to choose between the firsts and the lasts, my option was, is and will be clear: the firsts, students or not.
At last these are forums, open to the community, neither guards nor policemen, just a few rules, being the common sense the major one. Forums at last. Nothing more.
Regards!
