Just don't bot anything you don't want to lose, jagex aren't bad at catching botters - so many people doing services for me have received bans lol (dw, throwaway accounts with payment after completion)
I wouldn't, to answer your question.
My friend got permed for his first offence because he botted a lot. Honestly just don't do it if it's not a throwaway suicide bot.
If you bot a lot, you will get permed on first offence no matter what. Mild botting should only get you a 2 day after it has expired.
