Ripperstore — Register Invite

I need to verify if there's any official information about RipperStore requiring an invite for registration. Since I can't browse the internet, I'll rely on my existing knowledge. From what I remember, RipperStore does require users to have a jailbroken device to access the app store for their tweaks. However, registration might not be a standard feature. If there's a new registration system with invites, it's possible that the developers are trying to track users or prevent abuse. I should present the information accurately but also highlight the legal risks involved.
