I get it from reading reputable documentation and apply common sense and my field of expertise, which happens to be veryrelated. The question is, where do you get yours? At least it's entertaining.
Do you mind providing the reputable documentation?
Many people on a 'certain' forum claims that Warden doesn't scan other processes, that and I haven't noticed any calls from Wardens code which would suggest it would do process scanning..
May I ask how exactly does Warden see how external programs interact with WoW?
Hmm, what do you mean by "If you're saying it just scans for bad add-ons or something,"? Warden scans for 'cheating' modules (DLL's) inside WoW, it also checks for modified code in certain places and so on..
Anyway, I could be wrong.
