For those who aren't aware of how many people get busted, and even little guys who have controlled deliveries, believe me they happen.
ERGO, we don't advertise every Tom Dick and Harry who sell gear.
Sometimes huge groups of busts happen all at once, sometimes its a couple here or there, but they do happen and its almost just a matter of time for many. The more private someone is, the safer they are. If you are opening your mouth at your local gym, you might already be a target. If you've had your mail monitored without you knowing it, because of sending W.U. to certain places, you might already be watched.
Better safe than sorry, and security by obscurity may make you look like a nut but you'll likely survive longer than a loudmouth. The reality is, this isn't 1985 anymore. Cover your ass, or find yourself someones piece of ass in Camp Fed.
