You know what happens when you remove a bot? They make another one, why? Because you didn't take their gil. It's a basic Sting operation, you allow the drones to do their work til they lead you to the Queen Bee. Once you find the Queen Bee you get this.

However if you just ban bots every time, you know what happens? The ones holding the gil just learn to play it safe, you don't lure them into a false sense of security and it's that false sense of security which allows them to catch nearly 39k accounts/users as noted above.

So ask yourself this, do you honestly think it's productive if the team were to just constantly ban 2-5 bots that most likely come from the same group while never finding the source? Because that's how you cause the issue to continue by going after the small fries.
