Blizzard computer identification? (MAC address, etc)

[Thongs]

Aside from IP address, what kind of information to identify your computer is being sent to Blizzard while playing WoW? It seems that my likelihood of having an account banned is directly dependent on the number of other bots currently running on my computer, even when I'm playing under IP addresses which would have hundreds of WoW players such as ping lowering services or a school network. So what kind of information is Blizzard receiving which could allow them to say "all 4 of these accounts are being run on the same computer"?

Thanks

There is code present for recieving hardware ID but I'm pretty sure that's for crash reporting. There are very few cases I've heard of where people get IP banned. It takes thousands of Frostmournes to be spawned in Orgrimmar for that to happen

Wow client can easy get hardware HDD ID, even without admin rights. It's just few lines of code.

I've continued to see a huge correlation between chance of being banned and the number of instances of WoW that I'm running. I'm running separate instances through a different IP, MAC address, and HD hardware ID, but it doesn't seem to make a difference. Is it possible that WoW is detecting other serial numbers, such as motherboard or RAM serial numbers instead?

Edit: I'm considering just running my instances of WoW through a virtual machine, and spoofing my MAC address in order to avoid potential detection via motherboard or RAM serial numbers. Is there any other way that they could be tracing me to my computer?

in all seriousness if this were the case, they would build their own custom hash from various things. They wouldn't just rely on NIC addresses and the HD id which is easily modified on the mbr.

As far I know, they aren't using anything to identify PC.

I got ban of all my accounts except one a few weeks ago. They were running on the same machine and were banned at same time. I know nothing about the method that blizzard use to determine that several accounts runs on the same PC, but there are a lot of them. In any case, I found full network adapters info with MACs, adapter names etc in wow process memory. This data appearing right after login and overwriting little by little by other unknown data when you continue to use game. May be this info used for making some kind of unique ID, that have sent to server.
Btw I tried to change MAC in network driver but found in WoW address space a new and the original hardware MAC. I dont know how WoW found harware MAC but this info present in registry.
And one more. I trying to intercept calls to GetAdaptersInfo and GetAdaptersAddresses windows API functions and found that wow not make this calls while login. So it use some other method.

P.S. I'm sorry for my bad english. I tried as best I could.
