Yes, a black flag in my case.
The information in books is nonscarce, in that it can be replicated at very little cost. It will be economically infeasible to try to stop distribution. The best way for you to get the upper hand is to come out as the legitimate, moral author of this; publicly and for yourself. You should set up a website and come out with a suggested fee for donations. There are other ideas too, like having previews and/or early releases for subscribers.
Of course you would still charge for the dead-tree book. Take a look at what Stefan Molyneux has been doing at www.freedomainradio.com. He lives entirely off the donations and subscriptions.
Hope this helps
