For piracy sites they first blocked the dns, dumb easily circumvented use the ip.
Then they blocked the ip, dumb easily circumvented spawn multiple versions.
They made linking to pirate sites illegal so they could block alternative versions.
They used to sniff all plaintext looking for tracker announces which look really distinctive.
But their latest methods are scarily effective.
They now do a man in the middle attack to decrypt ssl, and store all of it, if you use openvpn as a proxy without accounting for this they own you.
They also have the ability to send fake a close packet (I think its a corrupt packet and most ssl / ssh will just drop the connection) to stop you tunnelling out and around their censorship.
The average citizen could not possibly hope to overcome this censorship and I find my own abilities more and more challenged to stay ahead of them, they have a whole army of people that understand the internet better than me, eventually they will exceed my abilities, its only a matter of time.
