This is 100% detected by injection. No matter which way you slice it this program is and always will be detected no matter what the Staff/Mods tell you. The injection is used in order for HB to be able to interact with your World of Warcraft client. With so many users it doesn't matter what HB does. It will ALWAYS be detected and you are stupid if you believe anything else
I have been an honorbuddy user for 5 years and this is by far the most convincing wave that it's a direct injection detection, RIP Honorbuddy. But no matter what they'll keep telling you it's updated and safe in its current state. I can tell you now the programmers and debuggers at Blizzard are far, far, FAR better than the programmers that work here.
Good luck Honorbuddy, it was fun while it lasted but perhaps you should close up your doors because now it's just a big scam. You only have such lengths in between bans because users only receive reports and Blizzard only does huge waves when they decide to.
