North AmericaBlizzard Legal FAQ
Where can I send suggestions for games?
We appreciate the time and energy people put into making suggestions for our current and future games. Our company policy, however, prevents us from accepting for review any unsolicited ideas. Often in our industry, an idea being submitted will be identical or similar to one already used by other companies, or already being independently developed by or for a company. Therefore, Blizzard Entertainment® has adopted the unalterable policy of refusing to accept or look at any unsolicited submissions or ideas. You can post your suggestions under the appropriate category in the most relevant game forum: Legacy, StarCraft II, or Diablo III, Hearthstone, Heroes of the Storm, World of Warcraft.

How is it that Blizzard can distribute such large files to the public?
To distribute large files, such as cinematic trailers, Blizzard utilizes the Blizzard Downloader, which is a software utility that will make use of the "upload" capability of your computer to distribute the Program to other individuals who may also be downloading files from Blizzard. Note that this utility is only active when you are downloading files, and that only files associated with the file that you are downloading are uploaded. Blizzard will not upload any other files, or obtain any personal information about you as a result of this activity.
The Blizzard Downloader is based upon the BitTorrent open source, which is freely distributable pursuant to the MIT License, as follows:
