LU I guess this is how it works: When you connect to the site your ip address – a number that’s associated with your internet connection – is registered. It can be easilly set up that no one can open a second account from the same ip address, or that if they try to do so the mods will be notified.
You can still get around it if you use a different internet connection, say your smartphone. Also changing your ip is not that hard. I guess that’s what the mods had in mind when they said there was no confirmation.
Mods? did I get it right?
