Stop giving the authorities so much credit. One look at this website should tell you all you need to know about the effectiveness of this stupid law.

I can tell you, after the experience I had yesterday, I'm going to relish breaking this stupid law in the future.
Reviewing is fine, new law or no new law to be honest. Just once you're not stupid enough to reveal your actual identity here on the boards.
It's too difficult for the authorities to get your identity from here. Given they've to go the website to force them to cough up an IP address associated with an account here, then force the identity out of the Internet Service Provider. There's no legal framework to do such a thing, I mean the entertainment industry has tried it and failed miserably.
Of course they could shoehorn these police-state like laws through the parliament if they wanted to, and even if they did, the site being hosted in a different country gets around that just fine.
