In the next week that is coming up, Diablo 3 users will only have a limited amount of games they will be allowed to launch in a small period of time. Blizzard have decided to take this action because of all the bots that have caused them no end of problems. Also the hacking has played a big part in Blizzard’s decision to take this course of action.
They want the terms of usage to be respected and think this is the best way of going about that. On the official Battle.net forum, Blizzard said “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 3 game service in a way that violates the terms of use – for example, by using bots that create games in rapid succession.”
You can get in contact with Blizzard though if you are one of the genuine players and you will have to explain as to why you plan to create load of games up. You should receive a message by them saying that your input limit has been reached. That is when you will have to contact Blizzard directly and tell them the story.
