There is illegal, and then there is unethical. It's not illegal for me to view the emails of employees in my corporation as that is part of what I control and the emails themselves do belong to the corporation; however, it is unethical to do so, and will only be done through the proper channels of request and approval. In some situations unethical behaviour can lead to illegal or subvert behaviour.
You may not be bound to TOS on a student's educational facilities; however, that student is. It is *highly* probable that facility includes provisions for plagiarism in their TOS, and is likely not tolerated. They get caught, and they get a nice 0. Therefore, the request itself does fall in line with rule §1.4 asking to have software written that violates TOS on top of §1.5 which is specific provisions for homework assignments. Your complicity is simply enabling them to violate their TOS and that behaviour is very unethical.
The claim that not every one wants to be a web developer and therefore doesn't need to learn the material is absolute rubbish. I don't like to cook dinner either, but if I don't do it I'll starve to death. I could get someone else to do it of course, for a price, but in the long run that surely will cost me a lot, and I'll have learned nothing. Besides, what will I eat when a holiday comes around if nobody is around to make it? Just because you don't like doing something doesn't mean you shouldn't do it. In the same token, if the course material dictates that you will learn web development, than it is expected that you will learn the material. That is why a final exam exists to measure the knowledge of the material, and those that get others to do their work for them will often be exposed during this examination.
