I just got both accounts banned last night. Haven't used HB since the May 2015 banhammer when I got lucky and caught a 6 month suspension..I had bought a lifetime key so I decided it had been long enough, I'd start botting again. Came back, found out my lifetime was no longer active because they changed their lifetime key policy, so I bought a new key and the past few days I'd set the bot to level with Kick's leveling profiles on WoW2 using another pc, my old laptop, so that IPs couldn't be linked. Last night I was raiding with my guild and in the middle of killing Gul'dan both accounts were banned until August 1, 2018 at the exact same time for botting when HB never touched my WoW1. So yes, it can happen! They say they won't accept appeals, but I'm trying to fight the ban on WoW1 anyways, will come back and post results.
