The bot problem is rising and real.

[LalaRu]

The bots arn't on free accounts.

They are on real accounts with stolen credit cards, a few hundred years bought all at once, turned into accounts, and used before the card company catches on

Card is used to buy account time, it is charged back, and account goes banned automatically, without even the need to run a bot over it.

I don't think a resource so (illegally) valuable as a valid (stolen) credit card is being wasted to just create a bot on an online game. Whoever gets that resource will use it for more profitable uses imho.
