I have been running Herb+Mine in Tanana about 12 hours/day cycling between characters randomly every 30-60 minutes, and also doing their garrison's and running work orders through their barns for Savage blood. In between each of my toons running Herb+Mine in TJ I run a lvling toon for 30-60 minutes to help prevent exposure also making account run 24/7. Takes about 3 hours to cycle back to first character by that time most players that were in the jungle last time it was on will be gone. Brings in between 25k-35k/day or 2-3k per hour depending on market fluctuation. You'll need to also have the Stables on each toon so they can stay mounted, and have 670+IL to do it effectively.
I wasn't hit by December ban wave, and fingers crossed January tripwire either. Although does that mean this method is "safe" probably not, I wouldn't do it if your account is not disposable. This method should help with player reports and bans, but won't do anything if the bot is "detected" again. I just started running account 24/7 after January event because the account is disposable, and potentially flagged anyways.
