Battle.net announces Blizzard has once again brought out the banhammer to smite some wrongdoers in StarCraft II. Word is they have banned or suspended an unspecified number of accounts:

We recently issued a new round of account suspensions and bans to StarCraft II players who were in violation of the Battle.net Terms of Use for cheating and/or using hack programs while playing. In addition to undermining the spirit of fair competition that’s essential to play on Battle.net, cheating and hacking can lead to stability and performance issues with the service.

As always, maintaining a stable, safe, and secure online-gaming experience for legitimate players is a top priority for us, and we'll be continuing to keep watch on Battle.net and take action as needed.
