Staking, IRC dicing, or if your a pro mercher. Those are the only ways to goldfarm on RS now. You could also lure and/or hack but tbh that's too much effort.
For sure not dicing, because dicing isn't a very reasonable way. Also Invalid if you are suggesting hacking as an option for making money I would watch out for a ban/infraction because we don't take hacking lightly here.
