I’m sorry, I don’t see any such reply to your appeal. The response you show in that post is the only response I see so far. No mention of permanent anything.
The WoW license is suspended, not closed. We don’t generally apply additional actions to an account for appealing a penalty. The only exception would be if you were being abusive, but that isn’t common.
Sorry, we are unable to provide details on what we found outside of what was stated. Doing so would inform the developers of those programs that we are able to detect and action them which would cause them to change their behavior/methods.
I won’t say there haven’t been false positives, but generally when that happens it hits more than a single person. During an appeal, our staff does look into the action that was taken and work to verify if an error was made.
