I had an encounter with a human player using a botting program in Kugane near the Eureka NPC, when there were dozens and dozens of players next to it. I would change class from DoH to DoM and I would be instantly targeted and cured. I changed classes a few more times, and I even left and came back to check. I was instantaneously cured every single time with zero delay and I concluded that no human could have those reaction times.

I guess the player realised their character was making a lot of noise in a town because after a few moments they started moving around and stopped curing me (I was standing right beside them). The player had all lvl 70 jobs and I reported them to the STF.

Not sure if the player was banned or even punished. It was just interesting to note that this was an actual player, not one of these auto generated, random name bots. I guess if you are going to risk your account being permanently banned and losing everything by using one of these "undetectable" programs that is up to you. They are not undetectable and you are cheating to gain an edge.
