Bornakk has released some interesting news:
In our continued efforts to support fair gameplay in World of Warcraft and to provide a positive experience for players, we are currently taking steps to ensure fair and enjoyable competition in the Battlegrounds. Starting immediately, we will be issuing warnings and penalties, including suspensions and the removal of Honor points and recently acquired Honor rewards, for non-participation in Battleground games.

We are taking action against thousands of accounts immediately, and will continue to monitor these situations and regularly take action against violators. If you encounter a player in a Battleground who is intentionally not participating in the battle for an extended period of time, please help us track the situation and report the player as AFK. For information on how to complete an in-game AFK report, please go here. All reports will be thoroughly investigated, and corrective action will only be taken if the violation is confirmed.
