Site Blocking by Indonesian Government

Soon, The Government of Indonesian will block any access to p*rn content. This policy was backed up by majority in order to create a better effect of internet towards Gold Indonesia. How the method will be used? I guess (only guessing ... )

1. Making special regulation for internet access and every bussiness related to it.
2. Using DNS blocking
3. Using content filtering.. this will be a hard method
etc... (i'm so tired after the birth of my fist children)
btw, Indonesian government sites start to be defaced (you can read at detikinet.com)
