Bot farming is extremely competitive, very few people are keen on sharing anything too special about their success.
TRiBot is a very popular OSRS bot right now.
It has a wide selection of scripts and antiban features such as human based mouse movements, and "Looking Glass" which lets you bot through a "legit" rs client, versus the botclient.

You can use those as a starting point, and see what works for you from there.
When botting multiple accounts, people like to split their accounts over multiple IP addresses to avoid "chain bans". This done by using the proxy feature that most bots have.
You can learn more about proxies and where to get them at
www.RSBotSpot.com
Start small, experiment, trial & error, see what works for you.
Get more "reckless" over time, and get away with as much as you can.
Everyone finds their own preferred methods and techniques after practice.
Jagex has stepped their anti-botting game up a lot since the "glory days" of the early 2000s, but lots of people are still able to successfully farm with enough practice.
GL, Happy Botting.
