after botting for about a month on my main with 1500+ total lvl, I got caught just recently [my first ever ban for botting on RS in general]. it was a 2 day ban (Bot busting moderate). only premium scripts were used. delayed by a few days most likely. I used 4-5 different premium scripts + mirror mode - babysitted 100%. didn't bot for more than 2-4 hrs per day.
lately, I used stealth injection on certain occasions - my guess is, this is probably the reason behind my ban ( however, i'll never know for sure). the scripts I used were well made, close to flawless. I'm assuming its a matter of luck when it comes to down to botting on osrs. my main does have nice stats with some 99's. I think i'm done botting for now, lol
getting banned sucks, but just like in every other video game - if you cheat, you always run a risk of getting banned, right? =)
good luck to everyone else out there.
