Blizzard announced that they have banned more than 5000 players from their servers. Those players have cheated the multiplayer game as well as used hack to get advantages against those players who play on an honest way. They even announced that they will proceed with banning players who are cheating. Its unfair and they wont allow it any further.
You might think that 5000 players is a lot. Actually its not. Back in 2008 Blizzard even banned more than 350.000 players from Starcraft and Diablo II games.
I think a good step to make gaming a better experience without getting defeated by cheaters all the time.
