Quests aren't too hard tbh, just takes a lot of time. Also, I think writing the scripts for quests give the account that was used a higher risk of being banned since you do one thing, stand around while you write the code, do another quest thing, stand around some more. Looks suspicious and might get you flagged. If this turns out to be true, it would take MANY accounts just to complete quests like RFD. Although its just a theory I have.
