We consistently have people come and ask very detailed questions in the Ubuntu Forums. That is reasonable, since it is an excellent place to get help. Occasionally, it is painfully obvious that the question(s) being asked are taken directly from a homework assignment, or something similar. The forum rules prohibit doing this, and moreso, the members of the community would rather a person actually learn the material they are expected to learn, and are willing to assist with hints or advice on where to look for help, but will almost never give direct answers to homework type questions.
We had a new example of this during this week. Someone was applying for a Linux sysadmin job and had the audacity to post the questionaire he was given by his prospective employer on our forums, asking our members to answer it for him. They didn’t, but the interviewer found the thread, and the job interview officially ended there.
