No, I don't think it's safe. I think they added something that is detecting HonorBuddy at this time, and all accounts that you value should stop botting until Bossland figures it out.
If Blizz added anything that detected HB, we all would be up shit's creek. If they really detected HB on your cpu, they would ban you, not give you a 3 hour suspension. What is being detected is unsupervised bots flooding BGs & running in to gankers & walls. Then their own team reports them. It's really just that simple.
