I'm going to keep this topic short, because there's not much to it. I've had over 10 mains, with 1000-1500 total (some even reaching 2000). All of them 90% botted, with some legit grinds.
But eventually all of them get banned. Usually first a 2 day ban, and 2 months later the perm ban arrives. Now that's just how I play. Currently I have a 1950 total account, with some really nice stats. But what I've realised it that you can not play legit and bot at the same time. So let's say, you play 4-5 hours legit, and bot another 3-4 hours. You WILL be flagged, because of your playtime. If you play for 30+ hours a week, and only botted 3 hours of them, Jagex will hunt you.
Pro tip: Either bot or play legit, do not do both. Either bot a few hours a day, or play a few hours yourself. But NEVER play a few hours legit, and then bot a few hours.
Please do not post anything regarding me wasting those account, that's my choice.
