When it says on the beta "use at own risk" Does that mean being able to get banned easier or does it mean its extremely buggy?
It's not detectable, but you may encounter glitches such as the recently reported "unable to chose a specific mount" bug. While these are inconvenient, it is a small price to pay to be able to use the bot during the period in which most botters don't bother. Like myself in most cases, I don't find losing a day or two from botting as a big deal. However I am not in the RMT scene anymore, and because of this I am not losing money by not botting. However many people do indeed get involved with the RMT and consider the down time of the bot as money lost. Depending on your involvement in the botting scene is really whether or not you should be using the beta.
