Stop being so Asura-centric. Other servers don't have nearly the number of bots that Asura does. It's not the game, it's the population of the server. Bots exist to farm gil to sell. The demand for gil is higher where there are more customers.
Well, you see. Sirmarki moved to Asura just few years after people already started botting and then he was constantly creating new threads demanding GMs to act up. Nothing happened and he demanded SE to add more space in the blacklist to block spammers. Not a good thing. Just how messy this game is now.
