Hey, everyone!
A though just came into my mind: what if all these PQR bans might have been triggered by PQI addon? PQI might be insecure as it sends some messages which could be read by blizzard.
After looking through the sticky ban thread I've noticed that the dominant majority of posters had PQI among their addons. In addition, my friends who were blatantly using PQR for months but never installed this addon were not banned.
As for me, I had this addon in my AddOns folder though it was disabled and, yes, I got 4 accounts banned.
What do you think?
Please, don't start the flame! I didn't post my thoughts in the sticky thread as they'll instantly drown in the endless flow of "I got banned" posts.
Edit: it turns out that 4 of my accounts were banned. Fourth one wasn't paid since the end of December.
