What would have happened if you declined to take the course? Do you think you "learned your lesson", or would you do something like this again if you had the chance?
They added the course as one of my graduation requirements, so I guess I wouldn't have graduated.
The lesson I learned is to not try to make others' lives easier. :P I definitely won't shy away from scraping whatever data sources I can get my hands on, but I probably won't share the results with large groups of people.
