If its as you say, then yes its a bot. No doubt about it. But Squenix ain't gonna do shit about it. They only ban RMT, suspicious large amount of gil being transacted and bot groups caught tele-farming Duties - any other outdoor action won't raise a flag. You see people telehack from npc to npc in the middle of a town, you see some people gathering with the AFK tag on - impossible to do for non-bots, the AFK is auto removed at the slightest hint of real keyboard/mouse/gamepad input.
