You can't BS it, you have to fill out a W9 form. I was going to sign up for it, but decided against it when my friend told me about it. She signed up as a guide and answered questions for quite a few hours. She only made a few cents during that whole time. Whether or not there is some sort of monetary promotion for answering a certain amount of questions is unknown to me, but it doesn't really seem to be worth the effort.
