1. Go to facebook.com
2. log in
3. then go to account settings and choose the language Bahasa Indonesian and save it
4. Now let the screen like that, and go find a indonesian proxy on http://www.freeproxylists.net/?c=id&f=1
5. When you have found a proxy;
you go to Firefox (the tab on top on the left side of your screen) --> to Options --> Advanced --> Network ---> Configure how firefox connects to the internet (you click settings)
There on 'manual proxy configuration' (HTTP proxy) you type in the IP ADDRESS and then the port and you check 'use this proxy server for all protocols'
and then click OK.
Now you go back to facebook again, change name, delete after name, and put one name only .. type your password for confirmation and click save. Congratulations, you got ONE name on facebook.
Some proxies might not work, some might be very slow.. I tried several proxies and I noticed some of them worked better on Chrome.
So I suggest you try on Chrome if it doesn't work on firefox
on chrome, you click on the item on the right top, then click settings, scroll down and click 'show advanced settings'
and then on network click change proxy settings - and then 'Lan Settings'
type in IP and port on proxy server - check the 'use a proxy server' and click OK.
the proxy server I used on chrome was 184.108.40.206 and the port 80
It worked for me, you can try and use it too or find a new one. it goes a kinda slow but that's why I say to let your facebook screen open in the start.. after you have managed to change your name, you simply turn off the proxy by unchecking the box
