Wouldn't it make more sense to offer to let users change the names of certain files, or window titles, rather then to discontinue altogether? Even on my site (MMOExploiters), I let people know the ways to get around these invasive programs - use a rehash utility, change the window title, increase the file size... I am sure there are methods for the users to use to get around these things. You could implement them automatically, or have them use established tools. On the other hand, when Asheron's Call, Rift, and DAoC got rid of the botters, the games died. I wonder if the same will hold true for WoW and their games. In the meantime, you can focus on other games still. No reason to put all your time into one game, when there are so many others to choose from now.
