I am very noob at this kind of thing but i was on http://whatismyipaddress.com/ and i tried hola on mozilla firefox and it changed the ip to what ever country i set it. Could that work for old school runescape? Also i used the proxy anonymous sites to surf and it did the same changed the ip.
But when i tried logging in on the same world on both accounts, one proxied one on my ip it gave me the too many connections on this ip :'( Thought it would work. If anyone can educate me on this that would be greatly appreciated.
