ffs i will settle this their is two types of ips a static and proxy ip (think soz) one of your ips is for your internet connection and one for your computer your internet one this one will never change but your static will. Runescape will look at your static ip and say hey 2 accounts on the came comp (IP) and not let u in. But it will allow it for 2 different on your same intent net provider ip. i am not sure about rules but account trading is not allowed and easily found out though unbalanced trades. wrote this fast soz if u can;t understand me
