"Glider is a tool that plays your World of Warcraft character for you, the way you want it. It grinds, it loots, it skins, it heals, it even farms soul shards... without you." -Quoted from mmoglider.com

Blizzard has taken Michael Donnelly, creator of Glider, to court over his code/creation in which they feel "both infringes the company's copyright and damages the game." The program simulates your character in World of Warcraft to grind xp, farm materials/gold, and earn reputation without the player actually being there. This violates Blizzard's User End License Agreement, so if you are caught using this program; you'll most likely be banned.

Mr. Donnelly has sold over 100,000 copies of this software and according to Blizzard earned 2.8 million US dollars(~1,770,855.55 EUR). Donnelly insists that his software is legal as it doesn't actually make any kind of copy of the game.

Blizzard released a statement last week on the matter:
"Blizzard's designs expectations are frustrated, and resources are allocated unevenly, when bots are introduced into the WoW universe, because bots spend far more time in-game than an ordinary player would and consume resources the entire time,".

"Blizzard permits its licensees to load the WoW game client software into RAM to play WoW. As such, Blizzard's licensees cannot violate Blizzard's exclusive rights under the Copyright Act to make copies simply by loading a copy of the program into RAM to play WoW," quoted from a statement from Michael Donnelly.

MMO Glider and sells for $25 USD plus a $5 monthly subscription fee that gives users additional support.
