On Balmung I've only witnessed 2 teleport miner bots (At the same location), and a single pocket of auto-farmers (with 6 or 7 thaumaturges in it, very close to the teleport miner bots). Needless to say I reported them all

I have noticed that on Balmung at least, the gilsellers are now advertising crystals as well as gil, which is no doubt the purpose behind the auto-miners
