Use proxies, with a maximum of 2 accounts per ip and never bot 24/7, there is a break timer in the osbot client that works like a charm. Also, when low level, frequently change scripts/tasks to make your bot look more humanlike.
There's nothing more obvious than a lvl 3 cutting yews for 20 hours straight. Also, as soon as you got your bots through tutorial island, get them membership. It'll lower the chances of ban A LOT.
