I've been working on making 3 main accounts with 2 of them being 2 day banned. I havent stopped botting even after the ban, I believe they do monitor your account, but the thing that I do differently now is I train atleast 6 different skills a day to spread evenly.
The reason I got caught was probably because I trained agility to level 30 in one run. But I think when it comes to that its hit and miss. My very first account I got it to 77 agility in one go.
So just keep caution really,
