Russian trolls posed as black activists on Tumblr and generated hundreds of thousands of interactions for content that ranged from calling Hillary Clinton a “monster” to supporting Bernie Sanders and decrying racial injustice and police violence in the US, according to new findings from researcher Jonathan Albright and BuzzFeed News.

While Facebook and Twitter continue to face intense public and congressional pressure over the activity from trolls working for the Russian Internet Research Agency, Tumblr has somehow managed to escape scrutiny. But the blogging platform was in fact home to a powerful, largely unrevealed network of Russian trolls focused on black issues and activism.

“The evidence we’ve collected shows a highly engaged and far-reaching Tumblr propaganda-op targeting mostly teenage and twenty-something African Americans. This appears to have been part of an ongoing campaign since early 2015,” said Albright, research director of the Tow Center for Digital Journalism at Columbia University.

No surprises there, then.

It’s funny how history repeats itself. After Germany’s defeat in WW1 the Dolchstoßlegende conspiracy theory — the idea that the German Army did not lose World War I on the battlefield but was instead betrayed by the civilians on the home front was widely believed and promulgated in right-wing circles in Germany. Accordingly, the German government leaders who signed the Armistice on November 11, 1918, were the “November Criminals”.

Now spool forward a century to contemporary Britain, where the lunatic fringe of the Tory party are preparing their very own Dolchstoßlegende. As my Observer colleague, Nick Cohen, puts it:

Patriots who shout about their love of country daily announce their hatred of every British principle that might constrain them. The rule of law and sovereignty of parliament? The Mail echoed every totalitarian movement since the Jacobins and denounced judges as “enemies of the people” for ruling that Brexit couldn’t be triggered without the approval of parliament. Academic freedom? A government whip demanded universities tell him what lecturers were teaching about Brexit. The right of MPs to follow their conscience? Liberal Tories received death threats after the Telegraph called them “mutineers” for not obeying orders and thinking for themselves. Now the civil service is having its ethics besmirched and neutrality threatened. Jacob Rees-Mogg and Steve Baker accused it of plotting to undermine Brexit by producing needlessly pessimistic forecasts. The lie was so demonstrably false even Baker had to apologise. Tellingly, Rees-Mogg did not. Unnervingly, he may be our next prime minister.

You do not have to know much history to recognise a stab-in-the-back myth in the making… So Brexit will not be defeated because the Tory right sold the British a fantasy but because judges, civil servants, saboteurs and mutineers subverted a glorious victory…

History is indeed repeating itself. But this is no farce.

LATER Simon Wren Lewis has a thoughtful blog post about one aspect of this — the way in which expert advice based on carefully-constructed models of what a post-Brexit UK economic would be like are being rubbished by the ministers who commissioned them. Wren-Lewis quotes a paragraph from an astute FT piece by Chris Giles (sadly behind a paywall) which nicely sums up the hypocrisy of this:

“Ministers now have a choice. They can opt for an honest Brexit in which they argue in public that people should pay an economic price for their policies. Or they can opt for a dishonest Brexit, pretending they have a secret plan for economic nirvana and trashing their own internal economic evidence. Ministers’ initial reaction in disowning the analysis suggests deception is the government’s central Brexit strategy. People talk about a crisis in economics. After this episode, it is the crisis in politics that should really concern us.”

Nice, perceptive column by Matthew d’Ancona:

Still, though, one continues to hear that [Theresa May] should stay where she is, as the only senior Tory who can realistically preside over the “constructive ambiguity” required by the Brexit talks – publicly demanding a clean break while quietly negotiating the complex, nuanced and unheroic deal that anyone remotely sensible knows is the only halfway palatable outcome.

The trouble is, she is doing no such thing. She is not the deft manager of meaning, soothing all sides and persuading each faction that its interests are being respected. She is the stuffed remnant of a once-optimistic prime minister, helpless in the midst of anarchic cacophony. This is government by taxidermy.

Yep. Amazing, perplexing — and alarming — to watch.
