Thanks for the responses!
2) How do I know based on proxy provider if I'm getting residential IP's or data center, do you recommend a provider that does residential?
3) Ok, i had registered it/played it on same IP. When you say " your proxy provider might be flagged " what would indicate to jagex that the account may be stolen, if its the same IP and a new account? Wouldn't that only happen if an account switches to another IP( they perceive that as someone just hacked a player, and logged in on a different IP )
