Playing legit is the only way to make sure you don't get banned. If you still want to risk it and bot, here are the types of scripts in order of ban rate:
1. Private scripts - smallest ban rate
2. Paid public scripts - larger ban rate, but still sort of small
3. Unpaid public scripts - large ban rate
Also, antiban isn't worth it - doesn't actually help, and causes a lot of unnecessary repetitive motions that jagex can track.
