Like the one-hit-kill a lvl 63 Tauren Warrior would lay down on a lvl 3 gnome mage, Blizzard's legal injunction against third party WOW spammer Game Dollar has been granted.
Blizzard argued successfully that the practice violated the game's EULA and Terms of Service and dimished the game for players which could result in a loss of revenue. This prevents Game Dollar from sending solicitations to WOW players, so offers of power leveling and in-game items will cease.
The injuntion is permanent. Chalk one up for the good guys.
