On a Perfectly Selfish Note....

On a perfectly selfish note: How can it be that I've had something along the line of 4,000 people join the group Ayahuasca in My Blood, and have only sold maybe 6000 copies. Not everybody who bought the book would want to join the group. Not even anywhere near two-out-of-three. So, this month, for instance, how did more than 50 people ask to join when I only sold 14 copies so far? Am I nuts or are there sites out there giving the book away for free and people are actually taking advantage of that? No artist should have his/her work used/misused/abused that way. No musician, no dancer, no film maker, no poet, no sculptor, and no writer. As I said, this is a perfectly selfish note. But if anyone has the answer, or an answer, I'd love to hear it.
