I got banned today on WoWbeez when buying the donor items. I came across this method which allowed me buying items and avoiding a ban. However some friends reported a ban after 15 minutes. If you like, give it a try. I recommend you, make a new account to see if it works. People only reported being banned for buying donor items. Buying T7 items should therefore not be a problem.
- start WoW, log in
- go to the donor vendor
- start PermEdit, start WPE Pro 0.9a
- Adjust all settings you need in WPE Pro
- Target WoW.exe and activate your filter
- Be quick in less than 10-15 seconds buy your donor items.
- Once you completed press ALT+F4 and exit WoW.
- Wait 5 minutes and log in again
Voila, you have your donor items. And be careful, you still might get banned. Do this on your own risk.
