I don't think they can detect HB/GB, they just banned 10 of my account this month (used HB/GB),i baby sit every accounts i bot. i appeal all of them 2 weeks ago and they only restore 3 off my account, then i never used HB/GB again, just manually everything after, i played like 3-5 hours a days 1-2 hours farmed 3 hours raiding, but today i lose all of my account 
. fvck blizzard. i have earned nothing in this 2 months, prolly lose like 18 account, and i leveled 2 new account and its not even hit 90 yet, its 89, and i leveling with my own hand, but still, today they banned all of my accounts. maybe my IP was flagged. who knows. i decide to quit, maybe someday i'll be back, thanks for everything to all HB team.
