Sounds good :)
But actually it is not possible to have free Rapidshare account. Even if you manage to hack someone’s account then Rapidshare will automatically detect based on IP address of the downloader and sends an email to owner with changed password. My account was hacked for 6 hours and Rapidshare has sent me an email with new password.
So practically you may manage to hack someone’s account for a day or two but for long run this will not work at all.
