So far i've heard of one 2day ban, but there may have been more. Simply put, it's all about how you use the script, not the script itself. For a detailed guide on preventing bans, take a look here: osbot.org/forum/topic/45618-preventing-rs-botting-bans/
Essentially, use generous breaks, play legit inbetween, invest in mirror if you can but don't worry toooo much if you can't, and if you've been banned on your ip before, it might be worth considering using a vpn/proxies.
hopefully that should clear a few things up!
