A great approach to be able to deal with bots would be to allow open world pvp, so that players could simply hunt bots down for a sport, which would not only make things alot harder for them, it would also force them to go for more drastic measures like cheating openly, which usually gets noticed a GMs rather easily.

But since FFXIV's EU/US community is as herbivore as it can get, i highly doubt we will ever see something like that.
