I attempted to automated my course registration process a few years ago. The registration software had a fixed limit of the number of pages you request before you get locked out. When you are locked out, a vague message appears about "attempts exceeded." Not knowing what to do next, I went to the registration office. They quickly realized what had happened and threatened me with disciplinary action because automatically accessing the registration system violated their vague interpretation of the school conduct guidelines (I also received a free lecture about how 'spiders' are border line illegal). After being further threatened with a "last day, last hour" registration timeslot until the sun burns out, I put on my best "I'm sorry" face and handed over a letter of apology and the 30 lines of code as they requested. They even had the courtesy to make snarky remarks about spending more time doing homework and less time trying to break their systems. WWW::Mechanize -- so easy it's dangerous.
