If you bot somewhere like dung where you can't be reported, yes. If you botting something like WCing then it's LESS safe to bot that long as you're open 2 many more reports. Thats my theory anyway.
You'll make like 100k/h tops at moss giants I'm guessing. I think I'd stick with whip since it isn't alot different for the cost.
Ontopic - yes & no. If a nerdraging bot hunt comes to the world your in, bye for 14 days. If not (they only cover very few worlds and mostly weekends), your fine and it's safe.
@100k an hour you will still have to pay 1m for rapier repair every 10 hours. Find a better spot or just buy whip. Also combat potions are a fantastic boost for training on a budget
