If reason is “Unauthorized cheat programs (hacks)” (most likely it’s this reason because you said you got perma and it’s most popular reason for perma atm) that’s blizz system triggered that you farm too much instances and think that you are “bot”. It is not about chat spamming, it’s not about GDKP or something else. It’s ONLY about a fact that you farmed dungeons too long and blizz system think that you are “bot”. Also looks like it’s not about reports, it’s about some blizzard internal algorithms
