I have seen these lala's and yes they are bots. Ran into one in the black shroud the other day. was a lala botanist and they were position hacking to every tree.

I'm pretty sure its one "legit" player with a bunch of bot alt FC's he uses to make gil.
If you look at one of those FCs you'll see a name that doesn't look like the rest. That's his main, I haven't reported it cause I don't feel like anything would really be done.
