I always laugh at the Government attempts to censor stuff on the internet, as it's just such a total waste of time and resources.
I mean, just take one example - the world renowned torrent website The PirateBay. There have been constant attempts to censor that and take it offline for almost a whole decade now, and yet it's never been more popular now judging by web traffic, and even though all ISPs in Ireland have the base Domain and IP address of the site blocked, there are countless proxy services popping up all the time that let you get around it in a single click.
I honestly couldn't care less if this is tried here, because I know it'll be an abject and unmitigated failure before it ever gets started.
