Hi Ufrore. https://docs.microsoft.com/en-us/windows-hardware/drivers/install/hardware-ids HWID stands for Hardware ID. There are a multitude of them; each device on your comp has a specific one that can easily be read/used. Most of them are hardcoded, which makes it that , while spoofing them is possible, the fact that they return to default values upon reinstalling the OS means that finding the REAL-DEFAULT value is also possible, beyond spoofing. Lots of people (most?) talk of HDID when they use the term HWID. HDID stands for Hard Disk ID, which is one of the most frequently used ones. If you want, google HDID changer and you'll find public spoofer programs. I'm afraid that answering your question is not possible. Cause no one knows, or no one will share, which ID's are used by blizzard to flag your comp. Might be MB, might be HD, might be any device on your comp or several of them. Hope you can find the info useful.
If Blizzard is using a HWID they're possibly using something similar to Windows Activation which uses the HWID specified in BIOS. Pirate versions of Windows use Grub to install a chainloader that spoofs the HWID as an OEM version like Dell with bulk licenses. Hackintoshes also use a similar technique to install MacOS on non-Apple hardware. It's conceivable to use this type of technique to change it but you'll also jack up your Windows Activation if you're using a legit copy of Windows. Another safer alternative to play around with this is to use VMWare. Specifically, look at how people have patched VMWare to trick MacOS installers into thinking they're running on legit Apple hardware. Personally, I would be very surprised if Blizzard is using any type of HW identification code per se to ban accounts. These ban waves really started with Overwatch and WoW was hit with the same detection technology as collateral damage. While not popular in the US, Internet Cafe's are extremely popular with Overwatch players in other countries where 100 different accounts can share the same computer.
Well, there is a big difference between flagging and banning. I don't think any smart person thinks that they ban accounts without having manual proof, except in the event of program/code detection (banwaves). But if they have 10 million accounts, and their systems flag 1 million for review , that would be very efficient for them, time and resource wise. The fact that they are flagging systems is obvious at this point, and I certainly agree it was something used in OW that has since been incorporated to WoW. Internet cafes, or shared systems and Ip's, are a minor fact, and easily identificable. More often than not, there are dozens or hundreds of different account connections from those specific Geolocations. So, it's not that hard to take them out of the pool, or whatever system Blizzard uses. Let's be logical, a 13 billion dollar-worth company must have some well-educated folks taking care of that stuff. They can handle it.
