AS EN said, you have to play smart and you will be okay. When lumberjacking and mining, use different rarely visited banks, make sure you have plenty of runebooks so you aren't seen at the same spot for a long time etc. I usually use a minimum of 8-12 books making sure if anyone does see me, it will be a long time before they see me again. I do not have my characters dump ore, boards, or blackrock either. If I don't want it, I trash it or donate it.
I have never scripted BODs so I would definitely listen to EN on that one.
