Is this a violation of World of Warcrafts Terms of Use or the new AddOn policies?
As far as we know, no. We do not do any internal memory reading or other hacks to the Warcraft client. This information is incorrect. The specific parts of the Terms that’re problematic are: “You agree that you will not modify or cause to be modified any files that are a part of a World of Warcraft installation” Tweetcraft modifies part of the WTF folder. “You agree that you will not create or use… any other third-party software designed to modify the World of Warcraft experience” TweetCraft is a third-party executable that “modifies the World of Warcraft experience”. The fact that it doesn’t edit the memory doesn’t matter. “You agree that you will not use any third-party software that intercepts, “mines”, or otherwise collects information from or through World of Warcraft” TweetCraft collects information (your outgoing tweets) from World of Warcraft. In summary, TweetCraft does all these things, so your account may be at risk. User beware. Source: http://www.wow-europe.com/en/legal/
