Use IP addreses to prevent users from being a guest.
This would work like an IP ban.
How this works:
The theory is that "All Guests are visitors trying out the site"
If they are new, their IP wont be in the system
BUT an active user's WILL be
So if ROBLOX detects that someone with the same IP is playing as a guest, they wll be kicked off of playing as a guest. |
