It's only ~8 cents an hour. If you think that is expensive then you must live in a straw shack in Africa. You can even make more than 8 cents an hour begging on the streets. Tbh I'd rather pay 8 cents an hour and never even have to worry about being banned than buy an unlimited auth and make that risk every second it runs.
If you care about the account, RiD is the way to go, if you don't mind your account getting banned and you having to start all over, then the risk is yours to take by using other bots. Simple as that.
RSBuddy's ProAlcher by Paradigm, FLAWLESS. Used it for countless hours straight with no ban or roll back what so ever, has great anti-ban actions and does random's great.
