If you create a level 3 to start wcing and do 10+ hours day then your gonna get banned w/e scripts/bots you use lol, if you have a 60+ f2p and do no more then 5 hours a day and have a good anti ban/random you can get away with rsbot all the way to 99.
RsBots (not RsBot) are the best bots to have. They cost money, but its better to pay one time then keep getting banned and having to make new accounts and start over.
