Well im pretty sure if they have any database management skills, they always back up their data. So if your account gets deleted by accident they could recover it. Now if it gets deleted becuase you are a moron and call jagex mods names or break to many rules, then its your own fault. I have no worries about this honestly. So to me its a null question. But to answer the question, yes i would start over. I have way to many friends from around the world to just up and quit.
