Interesting, I see that “autoflood” requires “messagequeue” which in turn could be used with AHK and the last one is against the Terms and is detected by Warden.
Anyway, Blizzard will not discuss with you what set off their detection. It is an either “yes will remain banned template” or “overturned template” or “will be sent to a specialist for further investigation template” - all by humans as Darth said.
