Paying people to do your homework

Every day when I skim through the RSS feed of new jobs at RentACoder, it's amazing how many of them are very obviously, even openly admittedly, people hiring people to do their homework. There's often ones saying that a job must be done urgently because the homework is due.

I find this infuriating. What are these people going to do when they get jobs, hire those out too? I can't help notice that if I were willing to take these jobs I could make a mint on very easy work. But I would never do it. Sometimes I want to make a fake account so I can bid on these, then never do the job, just to sabotage their efforts or at least slow them down. In any case, I find it frustrating I even have to see them. They should be in their own category (rather than combined with "Personal project") so I could filter it out -- though even if RentACoder had that category, I bet half the time the jobs wouldn't end up in it.

I'm not even in the education field. Why does this infuriate me so much?
