I used to bot on RS3 until recently when the bots only got you banned it can be quite profitable I made over $20,000 but now stake on RS3 as thats a lot better money if you know what your doing, I've made 5x more than I made botting staking in the same amount of time.
You should try staking, personally I've made over $50,000 just staking for fun some people you might wanna avoid are people doing ranges and using stalls though.
