The Warden's existence was acknowledged in March 2008, during the opening legal proceedings against MDY Industries. The lawsuit was filed in federal court in Arizona, and also listed Michael Donnelly as a defendant. Donnelly was included in the suit as the creator of MMO Glider, software that can automatically play many tasks in the game. Blizzard claimed the software is an infringement of its copyright and software license agreement, stating that "Glider use severely harms the WoW gaming experience for other players by altering the balance of play, disrupting the social and immersive aspects of the game, and undermining the in-game economy." Donnelly claims to have sold 100,000 copies of the $25 software.

Apart from controlling children, adults sometimes use parental controls on themselves. The company supports this kind of protection as otherwise the potential players or their supervisors may choose to uninstall or block the game permanently.
