well first of all I would recommend kminer from kminer.org because it is the EXACT SAME script for less money. The ppl from rsbots simply paid the developer of kminer to change the GUI to say rsbots.net and they also charge more.
Also, with kminer/rsbots it uses the reflection method so Fagex won't be able to ban you for botting with their detection system. The way you get banned is a mod sees you or a ton of people report you. Then they will look into your account and probably see that you're botting. Or you play for days and days and days without end and they may look into your account and see your botting.
So basically don't bot too much or in places where you will attract Fagex's attention and make them look into your account. Stay under the radar.
I think that the mine under lumbridge would be safe but I'm not sure kminer supports it.
