The dark side of Facebook
Dark money, as we have seen through the Trump election and the EU referendum, poses a grave threat to democracies all over the world.
Today we learn of a global web of alt-right pressure groups, think-tanks, Putin-controlled Russian trolls, and a US tech billionaire using their wealth and influence to propagate a cult movement around one particularly hideous goon in our country.
Stephen Yaxley-Lennon, aka Tommy Robinson, is founder of the English Defence League and a vile anti-Islamist. He is also the chosen puppet of this global fascist movement and, as of last month, an adviser to Ukip.
But it's not just the dark money that is funding Yaxley-Lennon. Today's Guardian investigation reveals that he has raised hundreds of thousands of pounds around the world, in broad daylight, through the Facebook Donate button - a tool solely designed for charity.
Facebook's contempt for democratic accountability is once again to the fore. Single-handedly its founder Mark Zuckerberg is - through his contempt for social responsibility - making the strongest case for an independent and powerful social media regulator.
Facebook has now withdrawn Yaxley-Lennon's access to the donate tool. But Zuckerberg needs to go much further.
Today I call on him to give a full explanation of how this dire breach of Facebook regulation occurred, pledge that it will never happen again, and, as an apology, make a match-fund donation to Hope not hate.
