Dang man I feel sorry for your lost. I've been using bots since 2009 on and off and I could say I never had a problem. Using bots is always a risk and is never guaranteed to never get you banned, however I do take my precautions all the time. Some of my tips to say safe include.
-Don't Bot for more than 4 hours, and if you do always take a break (I.E. Logout, do something different from what you were using a bot on before).
-Stay nearby your computer and talk to some friends over RS Private Chat. (Don't talk about Bots Lmao)
-Try and Purchase premium scripts as they are the best of any other category and have great anti-bans .
I've used it on all my mains and pure and still no ban yet !
