You're thinking one-dimensionally. It isn't just about how much money they make off each box sold -- it's about numbers reported to wall street. The amount of CD Keys sold in a month where botters is banned is significant enough to be controlled, for sure. I'm not typically a tin-foil hat kinda guy, but I'd say that much is obvious. Their shareholders want growth, and executive management will use any tools necessary to get it. Rest assured, with a modest amount of effort a "one button push" for banning botters is overtly plausible (The SQL necessary takes less typing than this post). Either they refuse to dedicate resources to this (which doesn't seem very plausible), or they police the situation with a reasonable level of control to gain what efficiencies they can from it (ie. more new copies registered = new players = growth = wall street happy = higher stock price).
