You also have to count that more than half of those 13k were botters, now we have less than that. The bans are coming more and more, and people stopped botting as they got what they want out of it and can't risk it any more. They opened up f2p, which made a lot more LEGIT players come over. In my opinion the number may have grown, but the people actually botting has dropped. Check when the servers are about to go offline thursday the number before and the number after. Used to the worlds would all get to under 50 people.
