I try not to run more than two on the same IP. Might have just been my luck but I've been chain banned twice while running three.
Key is "New Account" play the account legit just a little bit first and that will help a lot. Good luck!
About $20-$25 USD. Honestly without botting or skilling or drops you don't really have Runescape currency at all lol. My recommendation would be runecrafting nats at 44.
Guys honestly don't take it too seriously. I really wasn't trying to butt hurt anybody and you can tell from the tone this was all in good fun. The mods really couldn't care less about a topic like this as it doesn't sway their decisions at all. Just lighten up a little bit. I was just making a bit of a joke and everyone is getting all defensive.
The mirror client protects you at a code based level and can tell you first hand how much better the ban rates are using it as opposed to the injection method. And yes, it really is up to the scriptors now to make their scripts as human as possible.
