I've been using this bot called Shadowbot lately and have yet to be banned. You should check it out.

OSBot or TriBot are you best bets.
TriBot.
I have 2 Auth's (planning on buying another one soon) currently, and VIP on tribot, and it is well worth it. No problems with the client, and almost all users are very friendly and helpful!
Although TriBot will end up requiring you to pay for VIP, it is well worth it for flawless botting.
