This can be accomplished by paying attention to the least interesting skills first. I'd rather use runespan or bonfires, even though they are not as RS gold skill-based, but I'd rather be rewarded for producing quality work than making mass amounts of jewelry that diminishes its value.
If you feel it's against the rules, we will apologize and will remove the post. It's not harmful to anyone, and I'm not aware of any rules against "fun" bugs. It won’t be around for long, and it's not in the spirit of the rules to impose sanctions for players who exploit bugs that do not cause harm or impact to you or the game.
Tutorial Island is somewhat shaky however it is perfect to use for nostalgic purposes. This is just an idea that I had. It was a place that cheap OSRS gold many fondly remember. Do you ever wish to go back to Tutorial Island? Now is the time to do it!
