Sadly this isn't the case. I remember a case in the early 2000s were a UK guy was running a racist website hosted in the USA to be under their freedom of speech laws.But by proxying out of the UK you are outside of UK jurisdiction, so those servers don't have to comply with UK law.
But the UK government changed the meaning of the law and made publication from were it was transmitted from as opposed to where it's hosted at.
The government can track anyone successfully. It just comes down to how many resources will they put into to locating the person.
