The Diablo 3 developer plans to enforce a secret cap on how many games players can make in a given time, which will hamper potential botters and RMT sellers who engage in such practice.

Account owners who exceed the game creation limits will be given the message "Input limit reached" and will be prevented from making any more games. Blizzard said this is a critical way to stop "cheaters and botters" and will be meant as a support measure in between planned ban waves.

"In the near future, we'll be re-enabling the limit on how many games a player can create within a certain amount of time. We've further tuned and tested the conditions that trigger this limit to ensure, as much as possible, that it only affects those abusing the Diablo III game service in a way that violates the Terms of Use - for example, by using bots that create games in rapid succession," said Blizzard poster Vaeflare in a official warning post last week.

"The use of bots not only impacts the stability of the game service, but it also has an impact on the player-driven economy. While we regularly take action against accounts for the use of unauthorized third-party programs and bots, this additional measure will help us further preserve and protect the integrity of the game and economy in between ban waves," it added.

Diablo 3 ban waves began in early June with Blizzard issuing thousands of account suspensions and bans to players who were caught botting or hacking in-game, which are two violations under the Battle.net Terms of Use agreement.

The game creation limits are clearly an additional measure to discourage hackers and botters from circumventing the system. RMT sellers whose currency supply is sourced from these methods should feel the greatest pinch.

Blizzard said legitimate players who are affected by this newest measure could petition customer support to lift the game creation cap, subject of course to case-to-case basis approval.

"Once this change goes live, we're looking for your feedback to help ensure that the limit is working as intended. If you encounter the "Input limit reached" message and feel you should not have, please let us know how many games you were creating and why. This information will help us ensure the limit minimally impacts legitimate players while still protecting the game against bots," Blizzard said.

"We'll continue to tweak the game limit as necessary, as well as continue to go after the few cheaters and botters that are out there in other ways. Our goal is to help ensure that Diablo III continues to be a fun gaming environment for all of our players, and we're looking forward to hearing your feedback on this change once it goes live," said Blizzard.

Blizzard has not yet set a date on when the Diablo 3 game creation limits will go live, but we expect that D3 rates to skyrocket as RMT seller supply dwindles following its implementation.
