Tensta, let's see some clearing steps that you might have overlooked,
Are you aware that installing (re-installing) windows return most of your Hardware Information to its default values ? E.g. Your MAC address, your Hard Drive ID, they are all back to default.
You need to change again the MaC , HWID, again.
Also, check your IPs. Use any of the google options for IP checking. Are you completely sure they are being changed? have you checked them? maybe the range your ISP is providing is too small, making it easier for Blizz to see its you (flagged user IP-subnet) who is attempting to access their servers.
Do you use new WoW installations? full delete old installations, including the hidden files in program data and C:\Users\yourlocalusername\AppData\Local. Also delete the reg keys before reinstalling.
All these steps need to be done together. If you are doing 1 thing, then starting a new bot , banned, then doing another step, then starting a new bot, banned again, then another step,...you are doing it wrong. It's quite likely that blizzard uses advanced flagging systems that "mark" comps using several IDs. So you need to do them all together to get a real fresh start.
Even then, in order to be sure of which info Blizz does collect, it would require some time-consuming reversing all data going through all blizz applications , which is crazy. If there was an easy way, or someone had it figured out, we would know by now.
What is clear, by the fact that some people report real-name accounts not banned, is that they have some sort of registry which links comps / accounts / IPs to us, personally us.
How? that's what we have to figure out...
