You got super super lucky with only a 2 day ban, most people would have gotten a permanent ban. I highly recommend not botting on accounts with history, they are always watched. I highly recommend using master/worker mode for valuable mains, you did very well for an abyss runner.
As for the main, glad to hear the main survived, unlucky for the workers, I recommend having low levelled accounts with some history (quests/stats) instead of valuable accounts. Throwaway accounts are the general strategy here.
As for nat running on lower levelled accounts, did you try using the longer path (safest) instead of shortest one? There are two options in the setup window. I will run some tests to make sure they are both fully working as of the latest update.
Also guys, today there was a big update regarding inventory/banking - allowing you to eat/fill/drink while the bank interface is open, the bot will be undergoing a new version update supporting this new OSRS feature very soon ^^ Right now it still has the normal way of doing things, in the next version I will add an option to eat food while banking.
