A cheating botting program used in World Of Warcraft. It is currently in a court of law with Blizzard, the makers of the game.
What WoWglider does is perform tasks FOR YOU such as kill things, fish, level up your profession, farm honor, and more.
Glider IS a ToS violation in WoW and it will get you banned if the Game Master finds out you were using it.
Man 1: Man I love WoWglider! I got all the way to level 60 using it!
Man 2: Fucking botter. I hope you get banned for it, you fucking noob.
