Ya true but on the other hand its kinda in their court to make the in game scripting tools "cheat proof". They have no control over 3rd party applicaitons but they have full control over their in game product. Based on that I wouldn't really be overly concerned about getting banned for "illegal" add ons, based on the in game scripting tools. Has anyone ever?

And at any rate the auto follow thing isn't really all that helpfull. You want to hit auto follow right after you loot (if your main is not looting), not at some random intervals. I don't use it, just have a key near my trackball to hit after looting or when I want to autofollow.

Also TONS of add ons do repetitive searchs for like enemies in your area (obviously the code does it at some interval), items for sale in AH, and almost any kind of add on that warns you about somethign has to be checking at spicific intervals. Even threat has to be monitored at intervals.
