I add to that: many monks seem to think pretty short term. We're not just answering single questions, we're building an archive of questions/answers/discussions. If it were homework and the answer existed already online, no one would complain. The answers we provide outlast, one hopes, the context in which they are posed.

Though I completely understand not wanting to help cheaters. My high school graduating class's valedictorian got there, in small part, by cheating off my math tests. :(
