Someone who was a victim of GamerGate - which is almost the foundational moment for this whole thing - claims that the Alt-Right game Google, YouTube and social media with fake views/likes and other SEO tricks. They certainly use bots on Twitter. The operating principles of social media are "this is popular, this must be good", and "you like this, people who like this also like this, so here is this" and it is, I believe, relatively easy to manipulate those systems. I've seen in my own internet use, how I can quite aimlessly end up in a sewer of extremist views - the best example is how taking an interest in meditation on YouTube led to Sam Harris (who's written a book on meditation), and not long after I'm in serious Islamophobia territory and you can easily go onwards from there.
Have you seen the Guardian article on similar sorts of shenanigans?
The great British Brexit robbery: how our democracy was hijacked
I left Facebook the day before the Brexit vote because of the way it was going. I saw friends who were Leavers - and not racist in my (sometimes limited) experience of them - go through a sort of radicalisation process in the stuff they were posting links to. I think it was that period of time that I was introduced to Breitbart, a whole host of yer actual famous Fake News! stuff, and the like.
Kids have smart phones from, what age...? And they're getting all their news that way. And the right is winning in that area. Breitbart is by far the most popular news site on Facebook. The right does incredibly well on Twitter. Reddit... 4Chan... Some of the talk of what they've achieved is self-mythologising; some is - I believe - based on dodgy numbers; but they have a huge new platform and they are making very effective use of it, and using it to pull themselves into mainstream media and into mainstream political life. I've interacted with young people online - in forums and comments - who have a completely different set of facts.
I'm not sure what the answer is, but in production values, style, and often content, they are doing very well online at the moment. I think the left should start to play the same game by the same rules. And quickly to be honest.
