It is not legal to storage-sweep customer´s private computers, just because you as a firm wants to get rid of third party programs injected into the game.
It is neither legal to look for Windows Processes like HB.exe (but i can assure you that a lot of firms do this anyway, but they just can't ban you for it, because they are not allowed to use this argument in a ban reason/court).
- Why is this illegal? Because what processes you run on your computer, is your private business, and not Blizzard´s.
The main way Blizzard can detect the program is to analyse the interface between the game and other processes. Looking for injections and API's which are listening to the game features and such. Is this different than looking for the HB.exe process? YES! A lot, and that's why it's hard to detect, but both Blizz and the HB team has some skilled-ass programmers/reverse engineers.
All games have an interface you can hook onto, if you are a skilled enough programmer.
A storage (HDD/SSD etc.) sweeper would be detected so fast you wouldn't even see Blizzard getting torched to the ground. No succesful game firm is stupid enough to go bankrupt because of illegal sweeping of peoples private storages.
I repeat: Honorbuddy is illegal to use, but legal to have installed, and don't listen to all the dumb-nuts trying to tell you anything different.
Blizzard: "Bots are destroying the economy due to unbalanced inflation"
... People came into Legion with bags full of millions of goals, and they think that BOTS are creating the auction economy havoc? Doh...
Depends on where Blizz has put their anti-c h e a t.
It would be stupid only to have it in the Launcher, but I actually have no clue if there is anything implemented in the launcher.
Therefore, i have always had the launcher closed when i've had WoW opened.
Feature: "Close launcher when launching the game" in the application.
