LONDON — Manipulated Twitter accounts, doctored videos, dodgy websites, and questions of foreign meddling: In just six weeks, the campaign leading up to Britain’s general election this Thursday has had a taste of what the dark arts of online campaigning have to offer.
But in addition to concerns about material originating with shadowy groups or Russian operatives before one of Britain’s most important votes in a generation, a surprising amount of questionable online behavior has come from the political parties and candidates themselves.
The use of disinformation techniques by political leaders, particularly the Conservative Party led by Prime Minister Boris Johnson, points to an evolution in how the Internet is being used to grab attention, distract the news media, stoke outrage, and rally support.
And it is not just professionals who are creating false or misleading campaign material online. Just about anyone can put it together, and that is exactly what seems to be happening.
“It’s the democratization of misinformation,” said Jacob Davey, a senior researcher at the Institute for Strategic Dialog, a London group that tracks global disinformation campaigns. “We’re seeing anyone and everyone picking up these tactics.”
And with polls suggesting that voters are shrugging off accusations of online trickery — and Facebook saying that it will not screen political ads for accuracy — experts said the tactics were likely to further enter the mainstream in Britain and elsewhere.
“This is the election where disinformation was normalized,” Davey said. “A few years ago people were looking for a massive coordinated campaign from a hostile state actor. Now, many more actors are getting involved.”
Britain’s election provides an imperfect comparison to the upcoming presidential election in the United States, where the process lasts more than a year and the campaigns are better funded and more digitally sophisticated.
But the experience in Britain provides a preview of the unruly online battle brewing across the Atlantic, as those seeking to influence voters become more cunning about reaching people through Facebook, Instagram, Twitter, YouTube, and WhatsApp.
Labour has been drawn into the maelstrom, with its leader, Jeremy Corbyn, citing documents critical of the Conservatives that turned out to be linked to a Russian disinformation campaign.
But watchdog groups in Britain have singled out the Conservative Party in particular for its use of manipulative Internet tactics. Last month, the party apologized after spreading a video edited to make it look as if the opposition Labour lawmaker in charge of the party’s Brexit policy could not answer a question about exiting the European Union.
It then dressed up one of its Twitter accounts to look like a nonpartisan fact-check group, drawing a warning from Twitter. Later, Conservatives bought ads on Google so that in searches for Labour’s policy manifesto, the top result was a website that criticized the proposals.
The actions appeared designed to be easily discovered, provoke outrage and distract the news media, said Jenni Sargent, managing director of First Draft, a nonprofit group that investigates online misinformation. She said that whenever journalists questioned Conservative Party representatives about the questionable tactics, they used the opportunity to criticize opponents in the Labour Party.
Most worrying are the actions of the mainstream campaigns, said Lisa-Maria Neudert, a researcher at the Oxford Internet Institute who tracks social media use in the British election.
“It’s about winning at any price,” she said. “The difficulty is so much of this is legal. Much of it is just falling through the gaps of the law.”
For all of the effort and attention devoted to it, disinformation’s overall influence on voters is far from clear. Researchers have struggled to precisely measure how much people are swayed by what they see in their social media feeds.
Britain’s election is the first major campaign since Facebook said it would not fact-check political ads from candidates and political parties. Sam Jeffers, a cofounder of Who Targets Me, a group that tracks Facebook political advertising, said there had not been the flood of disinformation that many had feared. Yet he said there were a lot of misleading online ads, some from new outside groups whose financial backers are not always clear to the public.
As of Dec. 5, no party or candidate in Britain had spent more than 750,000 pounds (about $1 million) on Facebook ads during the campaign, far below what candidates in the United States typically spend.
Yet Davey of the Institute for Strategic Dialog said that posts spread among Facebook users were just as big a problem as political ads. The British election, he said, highlights the widening use of techniques to manipulate social media by candidates, parties, activist groups, and individuals around the world.
An Oxford University report this fall also found that governments were increasingly using online disinformation tactics.
With few rules around Internet campaigns, Davey said, it is hard for voters to know what content is legitimate and where the material originates. He pointed to several examples in which information that originated from unknown sources online had reached the mainstream.
In one, what claimed to be a leaked copy of a secret trade document between Britain and the United States was posted on the online forum Reddit. Corbyn, the Labour Party leader, later cited the document to support claims that the Conservative Party would weaken the National Health Service in a post-Brexit trade deal with the United States.
Last week, Reddit said the document had links to a Russian disinformation campaign, raising fresh questions about foreign interference in the campaign, though the document itself seemed to be accurate.
