I switched from WoW/Honorbuddy to FFXIV/Rebornbuddy less than a month ago. My WoW accounts are still active because the paid time has not expired even though I have cancelled all of my subscriptions. I was not banned on any of my WoW accounts. Since I have not played any of them in about 4 weeks, it seems to me that the Honorbuddy detection was probably a recent occurence.
