How to get a one named facebook account

While I don't use facebook myself, those of you who do can use this.

First, connect to an indonesian proxy or vpn
Then, save your settings.
Now, open your Facebook account's name settings.
Change your language to Bahasa Indonesian
Now, remove your last name and you're done!
Disconnect from the proxy/VPN and change back your language
Important Note:- Open your facebook account settings before connecting to the proxy
