This isn't the first time we've seen stories like this, but Blizzard, the makers of World of Warcraft are suing the maker of a Warcraft "bot"
that allowed players to automate certain activities. If this sounds familiar, you might recall people freaking out
over bots in Second Life as well. It all goes back to the same point that it's dangerous
to move real-world laws into virtual worlds. Those real world laws are designed to matter due to scarcity and the physical constraints of the real world. However, the whole point of a virtual world is that you're not limited by those constraints -- and you are only limited by the constraints programmed
into the world. If the creators of the world don't program in certain constraints, it makes little sense to force them on the world through a real-world legal process. Why not just program in those constraints? So, if such a bot is really a problem, program a way to stop it from working and kick the user out for violating terms of service. But to bring a real lawsuit (using copyright, no less) makes little sense here.
