Yesterday, Blizzard announced that they have banned several thousand Hearthstone accounts. These accounts were found to be used with third-software that automates the gameplay. The “botting confirmed” accounts will be banned until 2015, which is sort of surprising as Blizzard has been known to hand out lifetime bans in their other titles (like World of Warcraft).
Of course, this is good news to every that is playing the game for real. And, as always, they ask you to report any suspected botting activity to their Hacks team at firstname.lastname@example.org.
Long story short, they are watching… so keep your nose clean.
