My question is simple. What is to stop people from going to a website such as Instructables, and creating an account. What's to stop them at that point from copying a how-to word for word out of Instructables into a Word document. And at that point, what is to stop them from changing a lot of the wording around, and submitting it to eHow. Cash.
I didn't put question marks after my questions because, well, I think I jsut came up with a nice little blackhat method.
