Bots are still everywhere, questing and earning gil rewards to sell for RMT. They are still teleporting, still fighting mobs while underground and invisible, still doing everything they have been doing since 2.0.

And the market board bots are buying up cheap stuff to resell higher.

Whatever Square Enix is doing about botting isn't really effective. Botting is efficient and pervasive in this game, although mostly out of view of the veteran players. You mostly notice them while questing as a new player.

The game is probably working on code so old and so badly done that the devs have no programmic anti-botting capabilities. It's unfortunate but they are unwilling to overhaul the code in many aspects where it's clear the bad design is holding back the game and creating inconveniences and strange limitations for the player, while leaving the game wide open for bots.

The best way to play this game is to pretend you don't know the bots are infesting the game. The more you think about it the more you become disappointed.
