Let me shed a little bit of light on this, just from my little bit of experience. I used to be a GM for Maplestory for a little while. Most of the time, I would be looking place to place specifically for spam bots. Same with Atlantica. The problem is that these bots have made the users a lot of money, especially with players still doing RMT today. It's nothing to them to get banned - they'll just change one letter or number on a new character and go back to doing it. And it's not just one character - one account could have 8 characters under it. All they need to do is buy a 30-day subscription, grind out trials with a macro, and get stuff. It may not just be that the staffing is an issue, but that these accounts just make new ones. It's not hard to just get under a new IP, make a new account, and go again.
