So I've gotten a couple of questions about this both on the forums as well as here at the office. People want to know how to report really bad issues like exploits, hacks, cheats, etc.
According to the Forums Code of Conduct, under NO circumstances should a hack or exploit be reported on the public forums. Because of the sensitive nature of hacks/exploits, posting on the forums only ensures that other people are going to attempt to use them. Any poster who breaks this rule will have his/her thread deleted and the potential for a permanent ban.
If you find an exploit or think someone is hacking the game, please send a detailed e-mail to hacks@blizzard.com or fill out the form listed here:

Thank you for your due diligence with this. Reporting these issues is incredibly important, but at the same time please remember to report them through the secure channels.
