ATTENTION READERS OF THIS THREAD:
This lawsuit is old. really really old. a year and a half old.
Guess what it has amounted to so far? nothing.
Guess what it'll continue to amount to? nothing.
Sad that a year and a half old not-particularly-interesting lawsuit is just getting passed off as news. Oh well, free advertising for mmoglider i guess.
Move along...
As far as the illegality of mmoglider: there is effectively none. in fact, all of the illegality is on blizzard's end, due to their use of a tool known as "warden" which actively scans your RAM and potentially elsewhere to view what else is running on your computer. mmoglider in no way reverse engineers warden to subvert it; there is a bot that does that (ISXWarden) but a recent warden update broke that, and i'm not sure if it's been resolved yet. As far as how mmoglider works, it reads some information from the RAM that WoW is using in order to know where you are (it has its own x/y/z system), your health/mana/rage/energy, your target's name and stuff, and generally nearby objects (ie NPCs). From there, it essentially emulates keypresses and mouse usage and sends them to WoW. glider's avoidance of detection consists primarily of a rootkit in which it hides, and a tripwire system that lets it know if its being spied upon (basically keeps an eye on warden and makes sure to stay in the shadows)
While it'd be nice to see Blizzard get countersued for the trojan/spyware that is Warden, MDY Industries doesn't appear to be interested in doing so.
As for bots ruining the economy: not really... without them, prices would be significantly higher across the board for pretty much everything, and fluctuations would be significantly larger due to a smaller supply to the same demand.
In any case, reverse-engineering is legal. Writing software is legal. Violation of a ToS is not illegal.
And to the person that's going to reference the portion of the ToS where it says that you give permission to blizzard to snoop your computer with warden: i don't care. Clicking the accept button does not constitute a legal agreement and warden is still illegal.
