Are you sure about that? If you have other accounts use proxies to bot with them, so they're not botted under same IP.
Also the acc that had the two-day-ban, you should play 100% legit with it for a while let's say like ~2-4 weeks (or atleast I'll do this if getting any two day bans on my accs) and after that legit time start botting with small periods, and ofcourse not the highest ban rate skills/methods.
This won't guarantee you to be able to bot again, this is just my opinion about the whole system. That "2-4 weeks legit playing time" could be changed up for 6-8 weeks also.
