Something quite depressing is if we (HN crowd) find workarounds, most regular folks won't have the budget/expertise to do so, so citizen journalism will have been successfully muted by government / big media.
I grew up in a pretty deprived area of the UK, and we all knew "a guy" who could get you access to free cable, or shim your electric line to bypass the meter, or get you pirated CD's and VHS' and whatever.
There will always be "that guy down the pub" selling raspberry pi's with some deranged outdated firmware that runs a proxy for everything in the house or whatever. To be honest with you, I might end up being that guy for a bunch of people once I'm laid off from tech like the rest. :)
You should be worried. Don't underestimate the capabilities of the government bureaucrats. That "guys down the pub" will quickly disappear once they start getting jail time for their activities.
They cannot enforce laws against such "petty" crimes, the reason society mostly functions in the UK is because most people don't try to break the law.
Pretty sure the local punters would kick the cops out if they came for one of their own, especially if he got them their porn back.
There is no need for special efforts to enforce the law. Put a few people in jail - and everyone else will quickly find safer and more legal ways to spend their time. No one will do something like that unless they are confident of their impunity.
