I don't see the point of even approaching the issue, like I said, the numbers of afk flyers have to be fairly consistent among the 3 countries.
As Hitech said, it isn't hard to make a timed macro to type something now and again, or even to launch and then exit in a GV to stay active. I've done it in other games and it is simple to set up, I'd rather see HTC work on things that need fixing and not attempt to fix something that isn't broken.
