Bot farming is extremely competitive, very few people are keen on sharing anything too special about their success.
Start small, experiment, trial & error, see what works for you.
Try and behave as humanlike as possible when playing, utilize OSBot's Mirror Mode feature, use breaks, etc.
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.
