The Angry Exile: Sloppy filter

The Hangman

Into our town the Hangman came,
Smelling of gold and blood and flame.
And he paced our bricks with a diffident air,
And built his frame in the courthouse square.
The scaffold stood by the courthouse side,
Only as wide as the door was wide;
A frame as tall, or little more,
Than the capping sill of the courthouse door.
And we wondered, whenever we had the time,
Who the criminal, what the crime
That the Hangman judged with the yellow twist
of knotted hemp in his busy fist.
And innocent though we were, with dread,
We passed those eyes of buckshot lead --
Till one cried: "Hangman, who is he
For whom you raised the gallows-tree?"
Then a twinkle grew in the buckshot eye,
And he gave us a riddle instead of reply:
"He who serves me best," said he,
"Shall earn the rope of the gallows-tree."
And he stepped down, and laid his hand
On a man who came from another land.
And we breathed again, for another's grief
At the Hangman's hand was our relief
And the gallows-frame on the courthouse lawn
By tomorrow's sun would be struck and gone.
So we gave him way, and no one spoke,
Out of respect for his Hangman's cloak.
The next day's sun looked mildly down
On roof and street in our quiet town,
And stark and black in the morning air
Was the gallows-tree in the courthouse square.
And the Hangman stood at his usual stand
With the yellow hemp in his busy hand;
With his buckshot eye and his jaw like a pike
And his air so knowing and business-like.
And we cried, "Hangman, have you not done
Yesterday, with the foreign one?"
Then we fell silent, and stood amazed,
"Oh, not for him was the gallows raised."
He laughed a laugh as he looked at us:
"Did you think I'd gone to all this fuss
To hang one man? That's a thing I do
To stretch a rope when the rope is new."
Then one cried "Murder!" and one cried "Shame!"
And into our midst the Hangman came
To that man's place. "Do you hold," said he,
"with him that was meant for the gallows-tree?"
And he laid his hand on that one's arm.
And we shrank back in quick alarm!
And we gave him way, and no one spoke
Out of fear of his Hangman's cloak.
That night we saw with dread surprise
The Hangman's scaffold had grown in size.
Fed by the blood beneath the chute,
The gallows-tree had taken root;
Now as wide, or a little more,
Than the steps that led to the courthouse door,
As tall as the writing, or nearly as tall,
Halfway up on the courthouse wall.
The third he took -- we had all heard tell --
Was a usurer, and an infidel.
"What," said the Hangman "have you to do
With the gallows-bound, and he a Jew?"
And we cried out, "Is this one he
Who has served you well and faithfully?"
The Hangman smiled: "It's a clever scheme
to try the strength of the gallows-beam."
The fourth man's dark, accusing song
Had scratched our comfort hard and long;
"And what concern," he gave us back.
"Have you for the doomed -- the doomed and Black?"
The fifth. The sixth. And we cried again,
"Hangman, Hangman, is this the man?"
"It's a trick," he said. "that we hangmen know
For easing the trap when the trap springs slow."
And so we ceased, and asked no more,
As the Hangman tallied his bloody score.
And sun by sun, and night by night,
The gallows grew to monstrous height.
The wings of the scaffold opened wide
Till they covered the square from side to side;
And the monster cross-beam, looking down,
Cast its shadow across the town.
Then through the town the Hangman came,
Through the empty streets, and called my name --
And I looked at the gallows soaring tall,
And thought, "There is no one left at all
For hanging, and so he calls to me
To help pull down the gallows-tree."
So I went out with right good hope
To the Hangman's tree and the Hangman's rope.
He smiled at me as I came down
To the courthouse square through the silent town.
And supple and stretched in his busy hand
Was the yellow twist of the hempen strand.
And he whistled his tune as he tried the trap,
And it sprang down with a ready snap --
And then with a smile of awful command
He laid his hand upon my hand.
"You tricked me. Hangman!," I shouted then,
"That your scaffold was built for other men...
And I no henchman of yours," I cried,
"You lied to me, Hangman. Foully lied!"
Then a twinkle grew in the buckshot eye,
"Lied to you? Tricked you?" he said. "Not I.
For I answered straight and I told you true --
The scaffold was raised for none but you.
For who has served me more faithfully
Then you with your coward's hope?" said he,
"And where are the others who might have stood
Side by your side in the common good?"
"Dead," I whispered. And amiably
"Murdered," the Hangman corrected me:
"First the foreigner, then the Jew...
I did no more than you let me do."
Beneath the beam that blocked the sky
None had stood so alone as I.
The Hangman noosed me, and no voice there
Cried "Stop!" for me in the empty square.

Sloppy filter

I haven't blogged on the proposed webnanny/internet filter/Great Firewall of Australia plans down here for a while because things have gone a bit quiet. There have been enough colours nailed to masts, reputations staked and interests vested that I'm not all that hopeful that sense has been seen, particularly when it needs to be seen by a Communications Minister whose paternalist streak might be coming from both religious beliefs and leftie-ness, but it may be that it's been realised that a filter that promised much and failed to deliver would be worse than none at all. And I'm quite confident it would fail. Much of the illegal stuff is being shared by P2P anyway, and the filters proponents were forced to admit almost from the start that it couldn't do a thing about that. And then there's TORs and VPNs - basically it'll affect people who don't google for a way around the filter before the thing goes up, which is more or less everybody that doesn't need a filter because they won't be searching the web for baboon porn or whatever in the first place.

More interesting if you're a baboon, I imagine

But it's not just that because ISP level filters will be under attack from the other side too, as TalkTalk in the UK and some of its customers have found out.

Britain’s third-largest broadband provider has been promoting its new “HomeSafe” security product to its 4.1 million subscribers as a way of blocking pornography, viruses and other potentially harmful content.
Unlike the child safety products offered by other providers, it operates at the network level so parents do not need to install or maintain any software. The approach has attracted praise from MPs and campaigners seeking to restrict the availability of pornography on the web.
But for more than a week the system has failed to restrict access to Pornhub, which offers thousands of free explicit videos and is ranked as the third largest pornography provider on the web.
The failure was discovered by Cherith Hately, an IT expert and mother of three teenagers in south London, who tested the service last week. She found that on the Pornhub website the HomeSafe blocking page had been relegated to a small box normally reserved for advertising, leaving its adult content fully accessible.
“The ‘you have been blocked’ page has been diverted to an advertising slot within the Pornhub homepage thus opening access to it,” she said.
“The HomeSafe barrier has been knocked down, technically and literally. TalkTalk should inform all their HomeSafe customers that their children are still able to see pornography so that parents can supervise more.”

Far be it from me to tell me how to bring up your children, Cherith, and I'm sure you've already had the awkward conversation with your teens about which one had visited that site, but I'd say that parents should take this as an indication that the best filter system is the parents themselves.

A spokesman for TalkTalk acknowledged the failure and said technicians were working on a fix. He was unable to say whether the HomeSafe system had been deliberately circumvented by pornographers.

Perhaps not, but it occurs to me that if it had been to circumvent another filter that worked the same way it could affect TalkTalk too. In the Aussie context since what the nannies want is effectively ISP level filtering under government supervision all ISPs would have the same filter, and when a website manages something similar to what Pornhub's done to TalkTalk's HomeSafe this single point of failure would mean it won't affect just Telstra or iiNet or Optus customers - it'll be everyone. Hardly the end of the world because we'll be about where we are right now, but it does make the whole exercise seem a bit pointless.

“As the only network-level filter, TalkTalk’s HomeSafe is the most effective way of protecting children from content parents consider harmful,” the spokesman said.

No, I repeat: parents are the most effective way of protecting children from harmful content. The filter can't unplug the computer, withhold their pocket money or threaten to stop paying the broadband bill so there's no service whatsoever. But it can create a false sense of security.

“While no technical solution alone is able to solve the issue of child internet safety or be a substitute for parental supervision, we firmly believe that HomeSafe is a step in the right direction.”

Providing that false sense of security doesn't take over leading parents to assume that the filter is doing its job and little or no supervision is necessary, because when you concede that there's no substitute for parental supervision that would be a step in the wrong direction. Not that Britain's nannies are any more clued up about that than Australia's.

Under government pressure the rest of the big four internet providers – BT, Virgin Media and Sky – recently agreed to offer all new customers software to restrict which websites children are able to access, but stopped short of implementing network-level filters.
TalkTalk’s approach is meanwhile supported by the campaigners, and MPs including Claire Perry, a Conservative backbencher who is leading a parliamentary inquiry into online child protection. As well as network-level filters she wants broadband providers to switch them on by default.
“When I started campaigning to make access to internet pornography an 'opt-in', many industry experts said it was technologically impossible to provide a network-level filter,” Mrs Perry said.

You idiot. Of course it's impossible, we've just bloody seen that. This looks like it was circumvented at the other end without any effort on the part of the person sitting at home, and it's not like the person sitting at home doesn't have ways and means anyway. Look, I can't put it any better than an Australian blogger, Stilgherrian, put it nearly four years ago (my bold):

Real-world experience in everything from spam filters to the record industry’s futile attempts to stop copyright violations always shows that filters only block casual users. Professionals, the desperate or the persistent will always get through.

However if a politician demands a filter, pretty soon a shiny-suited salesman will appear, ready to sell him a box with “filter” written on the front. It’ll work — well enough for the demo, anyway.

“Look, Minister! Nice Minister. Watch the screen. See? Filter off, bad website is visible. Filter on, bad website gone. Filter off. Child in danger. Filter on. Child happy and safe. Filter off. Voter afraid and angry. Filter on. Voter relaxed and comfortable. Cheque now please.”

When elected nannies like Stephen Conroy here and Claire Perry in the UK wrap their heads around this and stop spunking taxpayers' money at things which at best will work until someone defeats them and at worst will never work at all they might start giving out useful advice. Advice along the lines of: the government can't stop your kids from seeing tits and arses and rooting baboons online...

... but if you get off your arse and look at what they're doing you can.
