You're using a free script which thousands of botters have access to. Jagex has already recorded all patterns for this script and the second anyone tries to use it and it does the same patterns = instant ban
You're not using mirror client
You're botting f2p, jagex watches f2p closely as well as newly created accounts
You're botting them all on the same ip, no one plays 6 accounts on the same ip doing the same thing
You're being cheap and trying to make money without investing any into premium/private scripts, proxies, mirror client. You'll end up using more electricity to keep your PC on than make money without investing any. Do not be cheap and invest, you end up making back loads after experimenting.
Good luck
