I haven't used OSbot in a super long time since I changed over to something else, but I don't see you having any issues with a skiller. I have a 10 hp skiller with 99 cooking, crafting, and fletching.
I also power mine fresh level 3's to 85 and sell them along with 10 hp pure magic accounts for people 70+ magic for cheap and have never been banned.
Not saying it won't happen since I haven't really kept up with the ban rates on other bots.
