I recently learned of this "Busy" thing, but I agree! I honestly don't remember any other game I've played ever having this much of an issue with RMT, though PSU (NA-PC/PS2) was hackers galore, which obliterated its economy. Fortunately, FFXIV has a comparably more stable economy, but the chat system needs work. My non-FC friends like to send me tells, so going busy is not an option for me.
