Battle.net post from Blizzard community manager Spyrian confirms that a new round of bans and suspensions has come down in Heroes of the Storm to discipline players found cheating and using hacks in the MOBA:

Cheating and using hacks while playing Heroes of the Storm or any Blizzard game will not be tolerated. These actions undermine the spirit of fair competition that’s essential to play on Battle.net, and can lead to stability and performance issues with the service. In Heroes of the Storm, cheaters ruin the competitive atmosphere not only for their opponents, but for their allies as well.

We recently suspended several accounts and issued permanent bans to Heroes of the Storm players who were found to be in violation of the Battle.net Terms of Use for cheating and/or using hack programs.

As always, maintaining a stable, safe, and secure online gaming experience is a top priority for us. We'll continue to keep a close eye on cheating in Heroes of the Storm and stamp out offending accounts to uphold the integrity of the game.
