RuneMob got me close to 1m xp in a skill very swiftly. Extremely professional service and would recommend to anyone! 10/10 would use again. Thanks bud!
I don't believe they will sue EVERY bot user, for just like Never Back Down said, it would cost them loads of money. I would really like to see if they actually go through with what they say.
RSBuddy.com is a good place for free bots. There are a lot of scripts to choose from. Just read the feedback on them and choose which one is best working at the time.
