One of my accounts was hit with a 72 hour suspension but after the 72 hours were up, I was able to farm 24/7 for over 2 weeks until my game time ran out. That account was never banned and is still frozen today. During this ordeal I had only one account running on my entire computer which was the account that was suspended for 72 hours but never banned. So just to make a few things clear, are all 72 hour suspensions player reported? Do GMs give a 72 hour suspension without player reports? Do player reports lead to a perma ban on the first time? Since this account was hit with a 72 hour suspension, it must have been players reported right? Is your account flagged after player reported 72 hour suspensions or is your account flagged after it was hit with a 72 hour suspension regardless of player reports or without player reports?
no one knows the questions to these answers. any answer given would be speculation and might mislead a botter to do something he or she wouldnt normally do. it is solely up to you to make decisions based on your personal knowledge and experience. many of us have had 20-30 accounts killed by blizz and now have a certain way of botting that makes us feel comfortable. but that is based on our personal experience. good luck and hope you find a way of botting that fits your playstyle and still stays under blizz's radar.
