has been swinging the banhammer in Heroes of the Storm going after those who have been using cheats and hacks. Specifically they've cracked down on the fog of war exploit discovered using the Nova.
"Cheating and using hacks while playing Heroes of the Storm or any Blizzard game will not be tolerated," they stated. “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.” Witness the map-hack below which Blizzard responded to.
“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.”
