Botting will always be a problem in mmos, and this is no different. The programmers, gil sellers, and just players using them, will usually be ahead of the company that makes the game, just too many of them. Heck, do a google search, and see for yourself, many bots will act just like players, not teleporting and making it easy to report.

I personally think companies should take the approach Blizzard took, sue them for more than it's worth for them to make the bots. Blizz has won in almost every case, I don't know if Square has the push, or legal reach, but i would love to see it.
